Find the solutions by using substitution method.
y squared= x squared - 32
x squared+ y squared = 40
------------------
y%5E2+=+x%5E2+-+32
x%5E2+%2B+y%5E2+=+40
Sub for y^2 into the 2nd eqn
x%5E2+%2B+x%5E2-32+=+40
2x%5E2+=+72
x%5E2+=+36
x = +6
x = -6
-------------
y%5E2+=+x%5E2+-+32
y%5E2+=+36-32
y = +2
y = -2
