3(x-2)-7(x+1)=-2(2x+1)-3(x+2)
We move all terms to the left:
3(x-2)-7(x+1)-(-2(2x+1)-3(x+2))=0
We multiply parentheses
3x-7x-(-2(2x+1)-3(x+2))-6-7=0
We calculate terms in parentheses: -(-2(2x+1)-3(x+2)), so:We add all the numbers together, and all the variables
-2(2x+1)-3(x+2)
We multiply parentheses
-4x-3x-2-6
We add all the numbers together, and all the variables
-7x-8
Back to the equation:
-(-7x-8)
-4x-(-7x-8)-13=0
We get rid of parentheses
-4x+7x+8-13=0
We add all the numbers together, and all the variables
3x-5=0
We move all terms containing x to the left, all other terms to the right
3x=5
x=5/3
x=1+2/3
