Answer:
Yes, you have to distribute.
Explanation:
2+5(x+3)-3(x-4)=x+2(2x+4)
2+5x+15-3x+12=2(2x+4)
Add the Numbers
2+5x-3x=2(2x+4)
Combine Like Terms, Then you can rearrange the terms for simplification. You should end up with an exation looking like this:
2x+29=5x+8
Subtract 29 from both sides. Simplify, then subtract 5x from both sides.
2x-5x=5x-21-5x
Simplify, then Divide both sides by the same factor. Simplify once more then you should have
x=7
Hope this helps ;)
