-5(x+1)-2=7(x-7)
We move all terms to the left:
-5(x+1)-2-(7(x-7))=0
We multiply parentheses
-5x-(7(x-7))-5-2=0
We calculate terms in parentheses: -(7(x-7)), so:We add all the numbers together, and all the variables
7(x-7)
We multiply parentheses
7x-49
Back to the equation:
-(7x-49)
-5x-(7x-49)-7=0
We get rid of parentheses
-5x-7x+49-7=0
We add all the numbers together, and all the variables
-12x+42=0
We move all terms containing x to the left, all other terms to the right
-12x=-42
x=-42/-12
x=3+1/2
