Here is an example of how to solve a multi-step equation. See if you can follow the steps that are written on the side.​

​

Let's Solve: -8(-8x - 6) = -8x - 22 + 2x

Step One: Distribute

Multiple Choice

After applying the distributive property to the following equation, what would be the result: -8(-8x - 6) = -8x - 22 + 2x

• 64x + 48 = -8x - 22 + 2x

• -64x - 48 = -8x - 22 + 2x

• 8x - 6 = -8x - 22 + 2x

-8(-8x - 6) = -8x - 22 + 2x

64x + 48 = -8x - 22 + 2x

Step Two: Combine Like Terms

Multiple Choice

After combining like terms in the following equation, what would be the result: 64x + 48 = -8x - 22 + 2x

• 64x + 48 = -10x -22

• 112 = -28x

• 64x + 48 = -6x - 22

-8(-8x - 6) = -8x - 22 + 2x

64x + 48 = -8x - 22 + 2x

64x + 48 = -6x - 22

Step Three: Move your variable to one side of the equation.

Multiple Choice

After moving the variable to one side in the following equation, what would be the result: 64x + 48 = -6x - 22

• 70x + 48 = -22

• 58x + 48 = -22

• 48 = 70x - 22

-8(-8x - 6) = -8x - 22 + 2x

64x + 48 = -8x - 22 + 2x

64x + 48 = -6x - 22

70x + 48 = -22

Fourth Step: Move your constant to one side of the equation.

Multiple Choice

After moving the constant to one side in the following equation, what would be the result: 70x + 48 = -22

• 70x = 70

• 70x = -70

• 70x + 70 = 0

-8(-8x - 6) = -8x - 22 + 2x

64x + 48 = -8x - 22 + 2x

64x + 48 = -6x - 22

70x + 48 = -22

70x = -70

Final Step: Solve by isolating the variable (multiply or divide)

Multiple Choice

What is the solution to the equation: 70x = -70

• 1

• 70

• -1

• -70

Multiple Choice

If we wanted to get the variable by itself, what is this first operations we would use to accomplish this?

7x - 8 = 27

• Add 8 to both sides

• Subtract 8 on both sides

• Subtract 27 on both sides

• Divide by 7 on both sides

Multiple Choice

After adding 8 to both sides, we would get:

7x = 35

What is our next step
