15 = (5)/(3) (x + 12)

Question

15 =
`(5)/(3)` (x + 12)

Answer 1

15 = 5/3(x + 12)

Using distributive law

15 = 5x/3 + 20

15 = 5x + 60/3

15 × 3 = 5x + 60

45 = 5x + 60

45 - 60 = 5x

-15 = 5x

-15/5 = x

-3 = x

Answer 2

x = -3

Explanation:

15 = 5/3 (x + 12)

Multiply each side by 3/5 to clear the fraction

3/5 *15 =3/5 *5/3 (x + 12)

9 = x+12

Subtract 12 from each side

9-12 = x+12-12

-3 =x
