Question

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

Answer 1

Respuesta:

m = 4

Explicación paso a paso:

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

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

14m + 21 - 5m = 8m + 16 + 9

21 + 9m = 8m + 25

9m - 8m = 25 - 21

m = 4

Answer 2

Respuesta:

4

Explicación paso a paso:

Considerando que "m" es variable

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

Suerte!
