Question

What is x if 72 equals 10x plus 2

Answer 1

7

Explanation:

10x+2=72 can be solved by the following manipulations

10x = 72 - 2

10x = 70

x = 70/10

x = 7

Answer 2

x = 7

Explanation:

72 = 10x + 2 subtract 2 from both sides

72 - 2 = 10x + 2 - 2

70 = 10x divide both sides by 10

70/10 = 10x/10

7 = x
