Solving Two-Step Equations Practical

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

Solve for x.

3x - 5 = 4

• x = 1/3

• x = 3

• x = -1/3

• x = -3

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