Answer:

  x +3 = x^2 +2x -4

Step-by-step explanation:

Straight substitution of the top expression for y gives you ...

  x +3 = x^2 +2x -4

__

This lets you rewrite the equation to standard form as ...

  x^2 +x -7 = 0

and find the solutions to be ...

  x = (-1±√29)/2

Corresponding y-values will be 3 more than this:

  y = (5±√29)/2
