Question

What is the value of r in the equation -1.5(4-r)=-12?
–6
–4
4
6

Answer 1

B -4

Explanation:

-1.5(4 - r) = -12

Distribute -1.5.

-6 + 1.5r = -12

Add 6 to both sides.

1.5r = -6

Divide both sides by 1.5.

r = -4

Your answer is -4.

Answer 2

r = -4

Explanation:

-1.5(4-r)=-12

Divide each side by -1.5

-1.5 / -1.5 *(4-r)=-12 / -1.5

(4-r) =8

Subtract 4 from each side

4-r-4 = 8-4

-r = 4

Divide each side by -1

-r/-1 = 4/-1

r = -4
