Solve 15 (s - 3) = 12s - 43

s = 2/3

Step-by-step explanation:

15 (s - 3) = 12s - 43

15s - 45 = 12s - 43

15s - 12s = - 43 + 45

3s = 2

s = 2/3

s=2/3

Step-by-step explanation:

15 (s - 3) = 12s - 43

distribution

15s-45=12s-43

minus 12s from both sides

3s-45=-43

add 45 to both sides

3s=2

divide both sides by 3

s=2/3

substitute to prove right

15 (2/3-3) = 12 (2/3) - 43

10-45=8-43

-35=-35
