Question

What is the value of x in the equation below?

40x + 120 = 720

21

18

15

12.5

Answer 1

The answer would be 15.

Explanation:

The first thing that you have to do is subtract 120 on both sides

40x + 120 = 720

-120 -120

40x = 600

Then you have to divide by 40.

40x= 600

600 ÷ 40 = 15

x = 15.
