Solve Equations

What was done to solve the equation?
(Line 1)          5x - 8 = 32
(Line 2)          5x = 40
(Line 3)          x = 8

• 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 by 5

• subtract 8 from both sides, then multiply by 5
