Answer: All I know is that x is equal to -1

Step-by-step explanation:

Answer:

X=-1 Y=0

Step-by-step explanation:

-10y+10y=0

Which leaves you with

9x = -9

and

5x = -5

Then you divide 9 off each side of 9x = -9 and 5x = -5

You will get

x = -1 for both

Then you might just try to find y but fail, thats because y is 0
