Answer:
The solutions are (-√6,0) and (√6,0)
(-√5,-1) and (√5,-1)
Step-by-step explanation:
We start with the equations:

and

Rearranging the second equation to make y the subject results in;

Substituting into the first equation gives us:


and 
The solutions remain as (-√6,0) and (√6,0)
(-√5,-1) and (√5,-1)
The correct option is the first one - refer to the image for the solution:
