Question

Solve 3(5m - 7 ) + 9 = 15/2​

Answer 1

Step-by-step explanation:

15m-21+9=15/2

15m x 2 = 15-8+21

30m = 7+21

30m = 28

m= 28/30

m= 14/15

Answer 2

Step-by-step explanation:

$3(5m - 7) + 9 = \frac{15}{2} \\ 15m - 21 + 9 = \frac{15}{2} \\ 15m - 12 = \frac{15}{2} \\ 2(15m - 12) = 15 \\ 30m - 24 = 15 \\ 30m = 15 + 24 \\ 30m = 39 \\ m = \frac{39}{30} \\ m = \frac{13}{10}$

m = 13/10
