Answer:
(-2, -1)
Step-by-step explanation:
first you must reorganize the equations so that one of them has x or y equaling to something
x - y = -1 --> x = y - 1
then substitute that in for x
3(y - 1) - 5y = -1
and solve for y
3y - 3 - 5y = -1
-2y = 2
y is -1
then plug it back in to an equation to find x
x + 1 = -1
x is -2
