-10=(-8+b)/2
We move all terms to the left:
-10-((-8+b)/2)=0
We add all the numbers together, and all the variables
-((b-8)/2)-10=0
We multiply all the terms by the denominator
-((b-8)-10*2)=0
We calculate terms in parentheses: -((b-8)-10*2), so:We get rid of parentheses
(b-8)-10*2
We add all the numbers together, and all the variables
(b-8)-20
We get rid of parentheses
b-8-20
We add all the numbers together, and all the variables
b-28
Back to the equation:

-b+28=0
We add all the numbers together, and all the variables
-1b+28=0
We move all terms containing b to the left, all other terms to the right
-b=-28
b=-28/-1
b=+28
