I have literally done this question like 10 times but I can't get it right. Can someone please help me out?

Solve the following expressions for z:
a) 2z/1+i - z/2+i = 25/11i+2
b) 4z/2+2i - 2z/i = 5/2+i

Is there any chance that the answer DOESN'T have an 'i' in it's denominator and your answer DOES have an 'i' in it's denominator?

a) z= 2 - i
b) z = (1-3i)/2

a) z= 2 - i
b) z = (1-3i)/2
That's the correct answer, but how did you get it?

It's just a matter of making z the subject and solving really.

Yeah, I've been doing that and I haven't gotten the right answer. Maybe it's my algebra, but could someone walk me through it, so I can see where I'm going wrong?
