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

Answer:

3y + 3z

Step-by-step 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  

Answer 2

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