From the first equation:

x^2 -2 y^2 =4        (1)

the second equation tells ya what x^2  is equal to....substitute that value into (1)

4y + 8 -2y^2 = 4

2y^2 -4y - 4 = 0

y^2 -2y -2 = 0          Quadratic formula will tell you y = 1 + sqrt3   and  y = 1-sqrt3

Use these values of y ...sub into (1) and solve for x 's......That should get you started....
