    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!!!!

    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
