This thing just driving me mad. Let say that we have these two equations
(875 + j300) X - (j1050) Y = 7580 + j 4375
-50 X + (50-25j) Y = 0
And both X and Y consist of real and complex number. Suppose the proper way to do it is
expand the X and Y into
X = real_x + imag_x * j
Y = real_y + imag_y * j
And substitute them into the equation, then solve by seperate the real and imaginary part.
-------------------------------------------------------------------
Ok, short story is, the solution I got from manual is
X = 3.7866 + j4.9598
Y = 1.0456 + j5.4812
While using inverse matrix method with matlab giving this solution...
X = 0.2746 + j0.8917
Y = -3.3469 + j7.243
Theoretically both solution seems to be correct (as approximation). But I just want to ask if anyone know the other way that will lead me to obtain the same solution as solution manual? (the first set of solution)
Since this work is to confirm and making sure that the answer from solution manual is correct before giving away to student. However, even thought I know who are incharge on this problem, but it is impossible to get to him at any moment
