Question

7m/10 =x +m/2 -6+ m-x/5 hallar x

Answer 1

Solución:

7m/10 = x + m/2 - 6 + m - x/5 
7m/10 - m/2 - m + 6 = x - x/5

x - x/5 = 7m/10 - m/2 - m + 6

4x/5 = 7m/10 - 3m/2 + 6
4x/5 = (14m - 30m)/20 + 6
4x/5 = (- 16m)/20 + 6
4x/5 = - 4m/5 + 6
4x/5 = (- 4m + 30)/5

4x = - 4m + 30

2x = - 2m + 15

x = 15/2 - m
