Question

- 12(x + 5)" align="absmiddle" class="latex-formula">

Answer 1

$-12(x+5)=144\qquad\text{use distributive property}\\\\(-12)(x)+(-12)(5)=144\\\\-12x-60=144\qquad\text{add 60 to both sides}\\\\-12x=204\qquad\text{divide both sides by (-12)}\\\\\boxed{x=17}$

Answer 2

Hello!

Explanation:

First, you had to do is switch sides of an equation.

$-12(x+5)=144$

Then you divide by -12 from both sides of an equation.

$\frac{-12(x+5)}{-12}= \frac{144}{-12}$

Simplify.

$144/-12=-12$

$x+5=-12$

Next, subtract by 5 from both sides of an equation.

$x+5-5=12-5$

Simplify.

$12+5=17$

Answer: → $\boxed{x=-17}$

*The answer must have a negative sign.*

Hope this helps!
