Answer:
You can't really determine anything here, as we'd need to know also the value of F(x)! Check again if there misses anything in this question.

You need to multiply both sides of the equation by the reciprocal of 3/4. The reciprocal is 4/3 and 4/3 multiplied by 9 = 12. So x = 12 because a number times the reciprocal is one.

Answer: (x, y) = (3, 4)
This is the same as saying x = 3 and y = 4 pair up together
======================================================
Explanation:
Subtract the equations straight down.
- The x terms subtract to 5x (because -5x-(-10x) = -5x+10x = 5x)
- The y terms subtract to 0 (because 2y-2y = 0)
- The right hand side values subtract to 15 (because -7-(-22) = -7+22 = 15)
After all that is said and done, we have this new equation
5x = 15
Divide both sides by 5 to get x = 3
Then we use this x value to find y
-5x+2y = -7
-5(3)+2y = -7
-15+2y = -7
2y = -7+15
2y = 8
y = 8/2
y = 4
Or,
-10x+2y = -22
-10(3)+2y = -22
-30+2y = -22
2y = -22+30
2y = 8
y = 8/2
y = 4
Either way, we end up with y = 4.
Overall, the solution as an ordered pair is (x, y) = (3, 4)
If you were to graph the two equations, they intersect at the location (3,4).
