Any number thats 8.5 or above
Answer:
The solution would be (-4, -2)
Step-by-step explanation:
To find this simply add the two equations together.
-9x+7y=22
9x-5y=-26
----------------
2y = -4
y = -2
Now we have the y value, we can solve for the x value.
9x-5y=-26
9x-5(-2)=-26
9x+10=-16
9x=-36
x = -4
