Question 168106: i am struggling with solving complex equations for x and y:
such as 3(x+jy)=9-j27

this if for an electrical degree course, quantitative analysis assignment.
Hopeing someone can explain so i can solve the rest of the problems as course is very fast meaning things are being brushed over very fast and it is an awful long time since i done anything of this level.
Regards
Kevin

You can put this solution on YOUR website!
3(x+jy)=9-j27
then
3x+3jy=9-27j
3x+(3y)j=9-(27)j
then
3x = 9 then x = 3
3y =-27 then y = -9
Answer: x=3, y=-9
