How do you solve \frac { m } { - 7} + 9= 11?

$m = - 14$

Explanation:

As per the question, we have

$\frac{m}{-} 7 + 9 = 11$

$\therefore - \frac{m}{7} + 9 = 11$

$\therefore \frac{- m + 63}{7} = 11$

$\therefore - m + 63 = 77$

$\therefore - m = 14$

$\therefore m = - 14$

Hence $m = - 14$ is the solution to this equation.

$m = - 14$

Explanation:

$\frac{m}{-} 7 + 9 = 11$

multiply both sides by$- 7$

$\therefore m - 63 = - 77$

$\therefore m = - 77 + 63$

$\therefore m = - 14$

~~~~~~~~~~
check:-

substitute $m = - 14$

$\therefore - \frac{14}{-} 7 + 9 = 11$

$\therefore 2 + 9 = 11$

$\therefore 11 = 11$
