How do you solve 9m - 51= 174?

Mar 5, 2018

$m = 25$

Explanation:

Add 51 to both sides
$9 m = 225$

Divide both sides by 9
$\frac{9 m}{9} = \frac{225}{9} = 25$

Now that we know what m is, we can substitute for m in the original equation to check our answer
$9 \left(25\right) - 51 = 174$
$225 - 51 = 174$
$174 = 174$ (correct)
