Solve for r. You must write your answer in fully simplified form.

-20 = - 15r

r = 4/3

Step-by-step explanation:

-20 = - 15r

Divide both sides by - 15.

-20 / - 15 = r

The negatives cancel, so

20 / 15 = r

Simplify by taking 5 out of the numerator and denominator. 20/5 = 4, 15/5 = 3.

4 / 3 = r

So r = 4/3.
