Choose the solutions of the following systems of equations x^2+y^2=6 and x^2-y=6

The solutions are (-√6,0) and (√6,0)

(-√5,-1) and (√5,-1)

Step-by-step explanation:

The equations are:

and

We make y the subject in the second equation to get;

We substitute into the first equation to get:

and

The solutions are (-√6,0) and (√6,0)

(-√5,-1) and (√5,-1)
