8-7(x-1)=2(x+5)
We move all terms to the left:
8-7(x-1)-(2(x+5))=0
We multiply parentheses
-7x-(2(x+5))+7+8=0
We calculate terms in parentheses: -(2(x+5)), so:We add all the numbers together, and all the variables
2(x+5)
We multiply parentheses
2x+10
Back to the equation:
-(2x+10)
-7x-(2x+10)+15=0
We get rid of parentheses
-7x-2x-10+15=0
We add all the numbers together, and all the variables
-9x+5=0
We move all terms containing x to the left, all other terms to the right
-9x=-5
x=-5/-9
x=5/9
