complex and real part of z

[aisha]

Find the complex and real part of z:
4z-z(3+i)=-1+3i

I think I am solving for z but Im having problems isolating it. Can some1 help plz.

Nevermind, sorry for confusing you.

Im not sure how to do that?

4z-z(3+i)=-1+3i

Factor out the z: z(4-(3+i) = -i + 3i ---> z(1-i) = -i + 3i

Hope you can figure out the next step (hint: it may involve the complex conjugate)

THANKS SOOOO MUCH Vincebs I got the answer thank you, I couldn't get the answer because I never thought of factoring thanks sooo much. :smile:

The correct answer to this problem is z=-2+i
