Question

I don’t understand and im going nuts, help.

Answer 1

4y+12 this is the answer I think honestly I have no clue I can’t promise it’s right math is not my best subject

Answer 2

First do distributive property.
Parenthesis is multiplication.
3(y)= 3y and 3(4)=12
After distributive property
Y+6+3y+12
Add 3y and y because they are like terms =4y
Add 6 and 12 because they are like terms
=18
So the full equation is 4y+18
You can’t add them because they are not like terms
