3%28x-5%29%2B2x=15
First, distribute the multiplication by 3 through the terms in parenthesis:
3x-15%2B2x=15
Add 15 to both sides of the equation. This gets you all the 'x' terms on one side of the equation and everything else on the other side.
3x%2B2x=30
Combine the x terms:
5x=30
Divide each side by five. This gets you x alone, and you are done:
highlight%28x=6%29
