2(2x-1)-2=2(x+7)+1
We move all terms to the left:
2(2x-1)-2-(2(x+7)+1)=0
We multiply parentheses
4x-(2(x+7)+1)-2-2=0
We calculate terms in parentheses: -(2(x+7)+1), so:We add all the numbers together, and all the variables
2(x+7)+1
We multiply parentheses
2x+14+1
We add all the numbers together, and all the variables
2x+15
Back to the equation:
-(2x+15)
4x-(2x+15)-4=0
We get rid of parentheses
4x-2x-15-4=0
We add all the numbers together, and all the variables
2x-19=0
We move all terms containing x to the left, all other terms to the right
2x=19
x=19/2
x=9+1/2
