write fortran program code for the above question using newton raphson method

Solve the following system of non-linear operations by any suitable method: 1. x^2 + y = 11 y^2 + x = 7 3.584428 -1.848127 x^3 plusminus y + 100 y^3 = x + 150 x^2 = 3xy - 7 y = 2(x + 1) -1.9266 -1.8533 Determine the complex roots by using Newton-Raphson method of the equation 1 + z^2 = 0 z_o = (1 + j/2) x_1 = -0.25, y_1 = 0.75
