Question 1187572
.


Add the equations.


As soon as you add them, the terms {-y^2}  and  {y^2}  will cancel each other.


You will get simple quadratic equation for x.


Solve it and get two answers/values for x.


Then substitute these values to any of the original equations.


You will get a simple quadratic equation for y:  it will give you two solutions for y.


Combine these solutions in pairs; be accurate with the signs of the values in pairs.


You should have 4 pairs (if there is no degeneracy).


They determine 4 solutions/answers.


This 4 solutions represent the intersection points of two curves, determined by the equations.
