First do the multiplication inside the parenthesis

(-y+15) + (7.2y-9)

Remove the parenthesis now

-y+15+7.2y-9

Simplify:

6.2y +6

So your final answer is [tex]\boxed{\sf{6.2y+6}}[/tex]
first remove the ( ) since there is a + sign before the ( ) the signs will not change work inside the ( ) -y+15+ 7.2y-9 6.2y+6
