# How do you solve 23=-4m+2+m?

Oct 5, 2016

$m = - 7$

#### Explanation:

Simplify the right side by collecting like terms.

$23 = - 3 m + 2$

That is : $- 3 m + 2 = 23 \text{ reversing the equation}$

subtract 2 from both sides.

$- 3 m \cancel{+ 2} \cancel{- 2} = 23 - 2$

$\Rightarrow - 3 m = 21$

To solve for m, divide both sides by - 3.

$\frac{\cancel{- 3} m}{\cancel{- 3}} = \frac{21}{- 3}$

$\Rightarrow m = - 7 \text{ is the solution}$
