# How do you solve 3( 3n - 4) = - 48?

Nov 9, 2016

$n = - 4$

#### Explanation:

Step 1) Expand the term in parenthesis:

$3 \left(3 n - 4\right) = - 48 \implies 9 n - 12 = - 48 \implies$

Step 2) Solve for $n$ keeping the equation balanced:

$9 n - 12 + 12 = - 48 + 12$

$9 n = - 36$

$\frac{9 n}{9} = - \frac{36}{9}$

$n = - 4$
