$4 + 14 y$

#### Explanation:

$11 + 15 y - 7 - y$
$11 - 7 + 15 y - y$
$4 + 14 y$

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:

$11 - 7 = 4$
$15 y - y = 14 y$

This is how you get the $4$ and the $14 y$.
