Answer 2

Hey there! 

In order to find the answer to this question you can do the distributive property to solve this particular problem

$-3(y) = -3 \\ \\ -3(5) = 15 \\ \\ -3y + (-15) \\ \\ \\ \\ 3(2y) = 6y \\ \\ 3(6) = 18 \\ \\ \\ \\ \\ -3y + -15 + 6y + 18$

Once when we do the distributive property we move onto the like terms 

Our Like terms: $-3y + 6y \\ and \\ -15 + 18$

So, lets solve our like terms 

$-3y + 6y = 3y \\ \\ \\ -15 + 18 = 3$

Finally!  we came to our answer

$Answer: 3y + 3$

Good luck on your assignment and enjoy your day
