Question

Solve for r. You must write your answer in fully simplified form.
-20 = -15r

Answer 1

r = 4/3

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.
