i dont know how to do this and its due at 4

Answer 1

r = -4

Explanation:

4r + 13 = -15 -3r

7r = -28

r = -28/7

r = -4

Answer 2

r = -4

Explanation:

4r + 13 = -15 -3r

Add 3r to each side

4r + 13+3r = -15 -3r+3r

7r +13 = -15

Subtract 13 from each side

7r+13-13 = -15-13

7r = -28

Divide each side by 7

7r/7 = -28/7

r = -4
