Answer 1

$\frac{x+m}{2}-6 + \frac{m-x}{5} = \frac{7m}{10}$

$\frac{5(x+m)+2(m-x)}{2*5}-6 = \frac{7m}{10}$

$\frac{5x+5m+2m-2x}{10}-6 = \frac{7m}{10}$

$\frac{3x+7m}{10}-6 = \frac{7m}{10}$

$\frac{3x}{10} +\frac{7}{10}-6 = \frac{7m}{10}$

$\frac{3x}{10} = 6$

x = 6*10/3

x = 60/3

x = 20

Answer 2

Explicación paso a paso:

$\frac{x + m}{2} - 6 + \frac{m - x}{5} = \frac{7m}{10}$

$\frac{x + m - 12}{2} + \frac{m - x}{5} = \frac{7m}{10}$

$\frac{5(x + m - 12) + 2(m - x)}{10} = \frac{7m}{10}$

$\frac{5x + 5m - 60 + 2m - 2x}{10} = \frac{7m}{10}$

$3x + 7m - 60 = 7m$

$3x = 7m - 7m + 60$

$3x = 6$

$x = \frac{60}{3}$

$x = 20$
