Solving:
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '30' to each side of the equation.
-30 + 30 + 8x = 110 + 30
Combine like terms: -30 + 30 = 0
0 + 8x = 110 + 30
8x = 110 + 30
Combine like terms: 110 + 30 = 140
8x = 140
Divide each side by '8'.
x = 17.5
