4+14y4+14y

Explanation:

11+15y-7-y11+15y7y
11-7+15y-y117+15yy
4+14y4+14y

First, I re-arranged the order (make sure that you keep the correct signs in front of the constant or variable e.g. -y, +15y, -7 and +11).

Then, I simplified:

11-7=4117=4
15y-y=14y15yy=14y

This is how you get the 44 and the 14y14y.
