Question

solve the following equation show your work 9 + 12m = 6 + 15(m - 1)

Answer 1

9 + 12m = 6 + 15m -15
9 + 12m = 15m - 9
9 = 3m - 9
18 = 3m
m = 6

Answer 2

9 + 12m = 6 + 15(m-1)
9 + 12m = 6 + 15m +(-15)
12m + (-15m)= 6 + (-15) + (-9)
-3m = -18
-3m/-3= -18/-3
m = 6

9 + 12(6) = 6 + 15(6 -1)
9 + 72 = 6 + 75
81 = 81
