This is simple to solve if you know the right terminology:
1.Term: Pieces of an equation separated by + or - signs
2. Similar terms: terms with the same set of variables ex. -8x^3 and 3x^3 but not`-8x^3 and 3x because x^3=x^3 You can combine these sets to form -5x^3 or -11x ^3 depending on if the terms they were a part of were being added or subtracted. When this happens, the simplified like term is put where the first term was.

combine the x^3's and you get -5
then combine the y^2 and you get -3
so the answer is -5x^3-3y^2
