Question

Solve 15=1.5r+3 check your solution

Answer 1

`8`

`1.5r + 3 = 15 \\ 1.5r = 15 - 3 \\ 1.5r = 12 \\ r = (12)/(1.5) \\ r = (120)/(15) \\ r = 8`

Answer 2

r = 8

Explanation:

15 = 1.5r+3

Subtract both sides of the equation by 3.

15-3 = 1.5r+3-3

12 = 1.5r

Divide both sides of the equation by 1.5.

12/1.5=1.5r/1.5

8 = r

r = 8
