-Solve the system of equations.
- 10y + 9x = -9
10y + 5x = -5

Answer: All I know is that x is equal to -1
Step-by-step explanation:
Answer:
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
