Let a, B, x, y satisfy ax + by = 3, ay - BX = 5, then (a ^ 2 + B ^ 2) (x ^ 2 + y ^ 2) is equal to_______ .

Given that the equations ax + by = - 8, BX ay = - 1 and X + y = - 1, 5x-y = 7 have the same solution, a B is determined

The solution of X + y = - 1,5x-y = 7 is x = 1, y = - 2
Because the equations {ax + by = - 8, bx-ay = - 1 and {x + y = - 1, 5x-y = 7 have the same solution
So substitute x = 1, y = - 2 into ax + by = - 8, bx-ay = - 1
A-2b = - 8, B + 2A = - 1
The solution is = - 2, B = 3
