Solve Two Step Equation

Did Sarah make an error? If so, which is the best description of her error?

• She didn't distribute correctly. The second step should read 3x - 12 = 24

• She didn't distribute correctly. The second step should read -3x - 12 = 24

• She didn't distribute correctly. The second step should read -3x + 12 = 24

• She didn't make an error.

Solve 2x - 3 = 1 

• 3

• 2

• 1

• -2

x - 62 = 123

How should you show your work to isolate the variable and solve the equation?

• Add 62 to each side.

• Subtract 62 from each side.

• Multiply each side by 62.

• Add 123 to each side.

The steps in solving 5b - 6 = 24 are: 

• Add 6 to both sides and divide both sides by 5

• Add 6 to both sides and multiply both sides by 5

• Subtract 6 from both sides then multiply both sides by 5

• Subtract 6 from both sides then divide both sides by 5

What is a 2-step problem?

• An equation where 2 steps are needed to solve it.

• An equation where only one step is needed to solve it.

• A problem with only one operation present.

• A problem where you find the square-root of a number.

Which equation has x = 5 as the solution?

• x + 15 = 10

• 2x = 5

• 2x = 10

What was done to solve the equation?

• add 8 to both sides, then divide both sides by 5

• add 8 to both sides, then divide both sides by 40

• subtract 8 from both sides, then divide both sides by 5

• subtract 8 from both sides, then multiply both sides by 5

10.    x / 2  - 5 = 3

• x = -2

• x = 2

• x = 16

• x = 8

x/5 - 13 = 20

• 145

• 165

• 180

• 190

3x + 1 = 10
