Answer:
(-8,-6)
Step-by-step explanation:
You add the equations together, the 2y and -2y cancel out. You isolate x, then plug the answer you get for x from that into one of the equations. The amount you get for y is the y-coordinate and the amount you had for x is the x-coordinate. To check, try putting the y value into the equation you didn't plug the x into before. If you get the same x value as you had before, it means it's correct, I think.
we are given
For finding inverse function , we do following steps
step-1:
Set f(x)=y
step-2:
Switch x and y
step-3:
now, we can solve for y
Multiply both sides by 9y-2
Add both sides by 2x
now, we can divide both sides by 9x
so, we get inverse function as
