Answer
$y$
Work Step by Step
Original expression:
$-(2x+y) -2(-x-y)$
Distribute the $-1$ in the first term (implied $-1$ from $-(x)$, and the $-2$ in the second term:
$-2x-y + 2x+2y$
(the last two terms are both positive because you are multiplying two negative numbers)
Add and subtract like terms:
$-2x + 2x = 0$
$-y + 2y = 1y$ or $y$
Thus, the simplified form of the given expression is:
$=0+y
\\=y$
