Answer:
(2,-3)
Step-by-step explanation:
-2x +3y = -13
-2x -5y = 11
Multiply the second equation by -1
2x +5y = -11
Add this to the first equation
-2x +3y = -13
2x +5y = -11
--------------------
8y = -24
Divide each side by 8
8y/8 = -24/8
y = -3
Now find x
2x +5y =-11
2x +5(-3) =-11
2x-15 =-11
Add 15 to each side
2x-15+15 = -11+15
2x =4
Divide each side by 2
2x/2 = 4/2
x =2
