+36916 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....
