Given that 217x + 131y = 913 131x + 217y = 827 then x and y are respectively

If x + 1/x = k and x² + 1/x² = k, then values of k are

If x + (1/y) = 1 and y + (1/z) = 1, then the value of z + (1/x) is

If x^3 – y^3 = 117/8 and x – y = 3/2 then the value of x^2 + xy + y^2 will be

If x is the largest and y is the lowest among ∜6, √2 and ∛4, then (x³+y²)/(x³−y²) is

If z = x + iy is a complex number such that iz = 2 + 3i, then the value of x − y is
