First combine like terms, 2x and 5x, to get 7x.
So 7x + 6 = 40

Then subtract 6 from both sides
So 7x = 34

Then divided 34 by 7
S0 x =34/7

Simplify to x = 4  6/7

I hope that helps! :3

x= 4.85714.......

Round that to 5. 

So the answer is 5 if it's rounded. If it is not.. the answer is 4.875....
