# How do you solve 5x + 30= 3( x + 4)?

$x = - 9$

#### Explanation:

$5 x + 30 = 3 x + 12$ (Take out the parentheses by multiply 3 by the numbers inside the parentheses)

Take $3 x$ to the other side because you do not want 2 separate $x$'s.

$5 x - 3 x + 30 = 12$

$2 x + 30 = 12$ (Simplify so that there is only 1 $x$.)

Take the 30 to the other side.

$2 x = - 18$

Now take 2 to the other side and divide it so now, $x$ will equal $- 9$.

$x = - 9$
