I know how to use "simple" complex number on TI-89
for example: 8+i3
but how about if there is two equations and we want to solve for x and y:
for example: (1+i1.5)x + i2.5y=20 and 11x + 15y=0
solve for x and y.
Is it possible to do the calculation using solve(
I tried to do it, but I kept getting "false" answer.
Any responds would be GREATLY appreciated.
