HW - Two-Step Equations Practice - A (RC)

What is the first step in solving two-step equations?

• Isolate the variable

• Apply inverse operations

• Simplify the expressions

• Check the solution

Which of the following is an example of inverse operations?

• Addition and subtraction

• Multiplication and addition

• Subtraction and division

• Addition and multiplication

What should you do if the variable is being multiplied by a number?

• Divide both sides by that number

• Add that number to both sides

• Subtract that number from both sides

• Multiply both sides by that number

Why is it important to simplify the expressions on both sides of the equation?

• To avoid errors and ensure the equation is balanced

• To make the equation more complex

• To eliminate the variable

• To change the solution

What is the goal when isolating the variable in a two-step equation?

• To have the variable alone on one side of the equation

• To eliminate all numbers from the equation

• To make the equation more complex

• To change the variable

Match the equation with the first step you would perform to solve it.

• add 32 to both sides

• 81 - 81x = -32

• subtract 81 from both sides

• -81 + 81x = -32

• subtract 32 from both sides

• -5x + 32 = -81

• add 81 to both sides

• -5x - 32 = -81

Match the equation with the first step you would perform to solve it.

• add 71 to both sides

• -1 = -71 - 64x

• subtract 1 from both sides

• -1 = 71 - 64x

• add 1 to both sides

• -71 = -1 - 64x

• subtract 71 from both sides

• -71 = 1 - 64x
