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