4(-8+1)+2b=3(2b-1)
We move all terms to the left:
4(-8+1)+2b-(3(2b-1))=0
We add all the numbers together, and all the variables
2b-(3(2b-1))+4(-7)=0
We add all the numbers together, and all the variables
2b-(3(2b-1))-28=0
We calculate terms in parentheses: -(3(2b-1)), so:We get rid of parentheses
3(2b-1)
We multiply parentheses
6b-3
Back to the equation:
-(6b-3)
2b-6b+3-28=0
We add all the numbers together, and all the variables
-4b-25=0
We move all terms containing b to the left, all other terms to the right
-4b=25
b=25/-4
b=-6+1/4
