Answer:

x=-4 , y=1

Step-by-step explanation:

-x+y=5

x-5y=-9

Add the two equations together to eliminate x

-x+y=5

x-5y=-9

-------------------

-4y  = -4

Divide each side by -4

-4y/-4 = -4/-4

y = 1

Now we need to find x

x-5y=-9

x -5(1) = -9

x -5 =-9

Add 5 to each side

x-5+5 =-9+5

x = -4
