Solve for x.

​4(5x−20)=−20​

Enter your answer in the box.

x =?

Answer 1

x = 3

Explanation:

4(5x−20)=−20 | Given

20x - 80 = -20 | Distribute the number on the outside (multiply all numbers on the inside by the number on the outside, 4×5x and 4×-20)

20x = 60 | Add 80 to both sides (do the opposite operation, if its a negative number add it to both sides)

x = 3 | Divide both sides by 20x (20x turns into x and 60 turns into 3 via 60÷20)

Answer 2

4(5x-20)=-20 should be x=3
