Solving for variable 'b'.

Move all terms containing b to the left, all other terms to the right.

Add '-2b' to each side of the equation.
10b + -2b = 36 + 2b + -2b

Combine like terms: 10b + -2b = 8b
8b = 36 + 2b + -2b

Combine like terms: 2b + -2b = 0
8b = 36 + 0
8b = 36

Divide each side by '8'.
b = 4.5
