Answer:
Step-by-step explanation:
x+5y=-27
-2x-5y=24
If the signs are the same u minus if they are different u add
So they are different were gonna add
x+5y=-27
-2x-5y=24
-1=-3
You cant divide it further x=-3
Next were gonna subsitute in any equation
x(-3)+5y=-27
-3+5y=-27
+3 to -27
-7+3=-24
5y=24
24/5=4.8 y=4.8
I hope this helps.
