Solve the following systems of equations: 2x - y = 3 and x ^ 2 + y ^ 2 = 2

Solve the following systems of equations: 1. 2x - y = 3 and x ^ 2 + y ^ 2 = 2 2. 2x + y = 4 and x ^ 2 - 2x + y ^ 2 = 0 3 4/x + 3/y = 2 and 4x + 3y = 25 (x - 1) ^ 2 + (y + 3) ^ 2 = 25 and x ^ 2 + (y + 1) ^ 2 = 10 5. x ^ 2 + y ^ 2 = 25 and - (4x - 3y) * (x - y - 5) = 0 6. x ^ 2 + y ^ 2 = 16 and 2x ^ 2 - 3xy + y ^ 2 = 0 7. x ^ 2 + y ^ 2 = 5 and xy = 2 8. x ^ 2 + xy = 5 and x - 2xy = 2 9. x + 4/y = 1 and y + 4/x = 25 10.
