-5%28w-4%29-%287%2B7w%29=-13w Start with the given equation.


-5w%2B20%2Bw=-13w Distribute.


-4w%2B20=-13w Combine like terms on the left side.


-4w=-13w-20 Subtract 20 from both sides.


-4w%2B13w=-20 Add 13w to both sides.


9w=-20 Combine like terms on the left side.


w=%28-20%29%2F%289%29 Divide both sides by 9 to isolate w.
