The TI-84 Plus CE is a graphing calculator that can be used to solve a variety of mathematical problems, including systems of equations. A system of equations is a set of two or more equations that are related to each other. In order to solve a system of equations, you need to find the values of the variables that make all of the equations true.

There are a few different methods for solving systems of equations on the TI-84 Plus CE. In this tutorial, we will show you how to use the Solve function and the Matrix function to solve systems of equations.

Entering Equations

The first step to solving a system of equations on the TI-84 Plus CE is to enter the equations into the calculator. To do this, press the [Y=] button to enter the Y= editor. Then, enter each equation on a separate line.

For example, if you are solving the system of equations

x + y = 5
2x – y = 3

you would enter the following equations into the Y= editor:

Y1 = x + y
Y2 = 2x – y

Using Parentheses to Group Terms

When entering equations into the TI-84 Plus CE, it is important to use parentheses to group terms. This will help to prevent errors when solving the equations.

For example, the equation

x + 2y = 3

should be entered as

Y1 = x + (2y)

The parentheses around the 2y term tell the calculator that the 2y term should be evaluated first.

Using the Solve Function

The Solve function can be used to solve a single equation for a single variable. To use the Solve function, press the [2nd] button and then the [Solve] button.

The Solve function will display a dialog box. In the dialog box, enter the equation that you want to solve and the variable that you want to solve for.

For example, to solve the equation

x + y = 5

for x, you would enter the following into the Solve function dialog box:

Solve(Y1 = x + y, x)

The Solve function will then display the value of x that makes the equation true.

Using the Matrix Function

The Matrix function can be used to solve a system of equations. To use the Matrix function, press the [2nd] button and then the [Matrix] button.

The Matrix function will display a dialog box. In the dialog box, select the [Math] tab and then select the [Solve] option.

The Solve function will display a dialog box. In the dialog box, enter the equations in the system of equations. Each equation should be entered on a separate line.

For example, to solve the system of equations

x + y = 5
2x – y = 3

you would enter the following into the Solve function dialog box:

5
3
1 1
2 -1

The first line of the dialog box represents the right-hand side of each equation. The second line of the dialog box represents the coefficients of the x and y terms in each equation.

The Solve function will then display the values of x and y that make the system of equations true.

Solving Systems of Equations

There are a few different methods for solving systems of equations. The method that you use will depend on the type of system of equations that you are trying to solve.

The following are the different methods for solving systems of equations:

• Graphing: You can graph each equation in the system of equations and then find the points where the graphs intersect. These points represent the solutions to the system of equations.
• Substitution: You can substitute the value of one variable from one equation into the other equation. This will create a single equation with one variable. You can then solve this equation for the remaining variable.
• Elimination: You can eliminate one variable from the system of equations by adding or subtracting the equations. This will create a new equation with one fewer variable. You can then solve this equation for the remaining variable.
• Matrix: You can use a matrix to solve a system of equations. A matrix is a rectangular array of numbers. You can use matrix operations to solve a system of equations by transforming the matrix into a row echelon form.

Advantages and Disadvantages of Each Method

The different methods for solving systems of equations have different advantages and disadvantages. The following table summarizes the advantages

3. Applying Systems of Equations

Systems of equations can be used to solve a wide variety of real-world problems. Here are a few examples:

• In physics, systems of equations can be used to model the motion of objects. For example, a system of equations could be used to model the motion of a ball thrown in the air.
• In chemistry, systems of equations can be used to balance chemical equations. For example, a system of equations could be used to balance the equation for the combustion of methane.
• In engineering, systems of equations can be used to design and analyze structures. For example, a system of equations could be used to design a bridge or a building.

The ability to solve systems of equations is an important mathematical skill that can be used to solve a variety of real-world problems.

How do I solve a system of equations on a TI-84 Plus CE?

1. Enter the equations into the calculator.

For each equation, use the following format:

`Y1 = `

where `` is the equation in terms of `Y1`.

For example, the equation `y = x + 2` would be entered as `Y1 = X + 2`.

2. Press [2nd] and [Y=] to enter the SOLVE menu.

3. Select [1: Solve].

4. Use the arrow keys to highlight the first equation in the list.

5. Press [Enter].

6. Use the arrow keys to highlight the second equation in the list.

7. Press [Enter].

8. The calculator will solve the system of equations and display the solution(s) in the Y-window.

What if I get an error message?

There are a few possible reasons why you might get an error message when trying to solve a system of equations on a TI-84 Plus CE.

• The equations are not in the correct format.

Make sure that each equation is entered in the following format:

`Y1 = `

where `` is the equation in terms of `Y1`.

• The equations are inconsistent.

If the equations are inconsistent, the calculator will not be able to find a solution.

For example, the equations `y = x + 2` and `y = x – 2` are inconsistent because they have different solutions.

• The equations are dependent.

If the equations are dependent, the calculator will only be able to find one solution.

For example, the equations `y = x + 2` and `y = x + 4` are dependent because they have the same solution.

Can I solve more than two equations at once?

Yes, you can solve up to three equations at once on a TI-84 Plus CE.

To do this, follow the steps above for solving a system of two equations, but select [2: Solve 3] instead of [1: Solve].

The calculator will then solve the system of equations and display the solutions in the Y-window.

What if I want to graph the solutions to the system of equations?

You can graph the solutions to the system of equations by following these steps:

1. Enter the equations into the calculator.
