12%2B3%285-4x%29=5-7%282x-5%29%2B8 Start with the given equation.


12%2B15-12x=5-14x%2B35%2B8 Distribute.


-12x%2B27=5-14x%2B35%2B8 Combine like terms on the left side.


-12x%2B27=-14x%2B48 Combine like terms on the right side.


-12x=-14x%2B48-27 Subtract 27 from both sides.


-12x%2B14x=48-27 Add 14x to both sides.


2x=48-27 Combine like terms on the left side.


2x=21 Combine like terms on the right side.


x=%2821%29%2F%282%29 Divide both sides by 2 to isolate x.
