Answer
$m = -25$
Work Step by Step
$\frac{3}{5}m = -15$
We need to isolate the variable $m$ by multiplying through by the reciprocal of the coefficient $n$ as shown below:
$\frac{3}{5}m \times \frac{5}{3} = -15 \times \frac{5}{3}$
Simplifying we have:
$m = -25$
Therefore, the equation has a possible solution at the point $m = -25$
