Question

Can someone help? It’s worth one point but there is only 3 questions so if I get it wrong I’m screwed

Answer 1

(3y+3z) = y+2y=3y+3z is the answer

Answer 2

3y + 3z

Explanation:

y + 2y + 3z you can only combine like terms y or 1y + 2y = 3y

3y + 3z these can't be combined because one is y and the other z
