what is the solution of the system of equations of x-y=-3 and x+y=5?

x-y=-3 x+y=5
y=x+3 0+y=5
x=3 0=0+y=5+0
y=x+3 y=5
y=3+3
y=6

x - y = -3

(0) - y = -3
-y = -3
(-1) -y = -3 (-1)
y = 3

x - (3) = -3
x - 3 = -3
x = 0

(0,3)

---

x + y = 5
(0) + y = 5
y = 5

x + (5) = 5
x + 5 = 5
x = 0

(0,5)

idk?
