-x+3=-(2x-4)
We move all terms to the left:
-x+3-(-(2x-4))=0
We add all the numbers together, and all the variables
-1x-(-(2x-4))+3=0
We calculate terms in parentheses: -(-(2x-4)), so:We get rid of parentheses
-(2x-4)
We get rid of parentheses
-2x+4
Back to the equation:
-(-2x+4)
-1x+2x-4+3=0
We add all the numbers together, and all the variables
x-1=0
We move all terms containing x to the left, all other terms to the right
