Answer:
7x-2=10x+x+6x
We move all terms to the left:
7x-2-(10x+x+6x)=0
We add all the numbers together, and all the variables
7x-(+17x)-2=0
We get rid of parentheses
7x-17x-2=0
We add all the numbers together, and all the variables
-10x-2=0
We move all terms containing x to the left, all other terms to the right
-10x=2
x=2/-10
x=-1/5
