How do i combine these using inverse operations to find what x =?

Let the equations be f(x) and g(x) respectively.
Now, equation f(x) has an equation solved for y.

Thus, we know a value for y.
We can then substitute that into the second equation.




Substitute f(x) for wherever y is in g(x):




Now, substitute x = 2 into f(x) to find the value for y.

Well is there a picture
