Answer:
There were 5 kids at a halloween party. They each took 5 pieces of candy. How many pieces were taken?
This can be used as a word problem because the negative signs can work as a symbol meaning "taken away". Also, -5 * -5 is 25, so it would correctly state that there were 25 pieces of candy taken away.
(4x-4y) + (-9x-4y) = -2 + -3
gather like terms :
4x-9x-4y-4y = -5
-5x-8y = -5
