Answer
x=3
Work Step by Step
In order to solve for x, we first need to get all of the terms with an x in them on the same side of the equation. Then, we need to isolate x by getting all of the numbers that are on the same side of the equation as x on the other side of the equation. Thus, we obtain:
$x=3.36-.12x \\\\ 1.12x=3.36 \\\\ x=3$
