Simplify the following expression:
2(4y + 5z)  10z

Let's see you try it first. If you don't understand these concepts, you need a private tutor.
(1) Multiply terms inside parentheses by the outside factor (2).
(2) Combine "like" terms. (In this case, there will be two terms that end withy z)
(3) You will note that two "z" terms are equal and opposite in sign. So the "z" terms disappear. 
2(4y+5z)10z
=8y+10z10z
=8y Answer
+10z and 10z cancel out as they are opp signs
