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 both sides by 5

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

Solve for x:

 $4\ =\ \frac{x}{3}-6$  

• x = 30
  

• x = 18
  

• x = -6
  

• x = 12
