no solution, friend

... thanks... friend... but i kinda need a solution....
OpenStudy (loser66):
I think you need the logic how to get "no solution" right? because it is no solution, how to have a solution?
OpenStudy (loser66):
times i to the first equation, the system becomes \[i^2x +iy =i\\x-iy=i\] \[-x+iy=i\\x-iy=i\] add them together, you have 0 =2i which is not right, so that there are no x and y satisfy the system--> no solution

-X+iY = 1
