This is a little harder than substitution. This is more like elimination.
Eliminate one unknown by subtracting or adding the two equations.
In this case I subtracted the two to eliminate y
and because you have an exponent you will have two answers as the line passes through the parabola.
The answers are (2,7) and (-1,4)
I took the liberty to show you how to solve by elimination in the picture below and graphed it out to help prove it.
It’s a pretty tricky problem, I hope this helps!
Good luck with your studies!
