X+y=-1 x-y=-7 by elimination

(x, y) = (-4, 3)

Step-by-step explanation:

x + y = -1 $|Rightarrow$ x = -1 - y

x - y = -7

Substituting the value of x (first equation) into the second equation, we get:

(-1 - y) - y = -7.

Simplifing, we get:

-1 -2y = -7

-2y = -6

y = 3.

Now that we know the value of y, we can solve the value of x by substituting y into the first equation. We get:

x = -1 - 3

x = -4
