Question

¿Cuál procedimiento resuelve la ecuación 7 (2m + 3) - 5m = 2(4m + 8) + 9 ?

A) 7 (2m + 3) - 5m = 2 (4m + 8) + 9
7 (5m) - 5m = 2 (12m) + 9
35m - 5m = 24 m + 9
30m - 24m = 9
6m = 9
m = 9/6
m = 3/2


B) 7 (2m + 3) - 5m = 2 (4m + 8) + 9
14m + 3 - 5m = 8m + 8 + 9
9m + 3 = 8m + 17
9m - 8m = 17 - 3
m = 14


C) 7 (2m + 3) - 5m = 2 (4m + 8) + 9
14m + 21 - 5m = 8m + 16 + 9
9m + 21 = 8m + 25
9m - 8m = 25 - 21
m = 4


D) 7 (2m + 3) - 5m = 2 (4m + 8) + 9
14m + 21 - 5m = 8m + 16 + 9
9m + 21 = 8m + 25
9m + 8m = 25 + 21
17m = 46
m = 46/17
