# Given K= a + 3mx how do you solve for m?

Nov 17, 2016

$m = \frac{k - a}{3 x}$

#### Explanation:

$k = a + 3 m x$

Bring $a$ to the other side it will be $- a$

$k - a = 3 m x$

Divide both sides by $3 x$.
In the right side $3 x$ will cancel with $3 x$ and you will be left with $m$

$\frac{k - a}{3 x} = \frac{\cancel{3} m \cancel{x}}{\cancel{3} \cancel{x}}$

$m = \frac{k - a}{3 x}$
