4w-5w%2B3%28w-7%29=-4%2B7 Start with the given equation.


4w-5w%2B3w-21=-4%2B7 Distribute.


2w-21=-4%2B7 Combine like terms on the left side.


2w-21=3 Combine like terms on the right side.


2w=3%2B21 Add 21 to both sides.


2w=24 Combine like terms on the right side.


w=%2824%29%2F%282%29 Divide both sides by 2 to isolate w.


w=12 Reduce.

Answer:

So the solution is w=12
