really comfused with the acts. Check it out please. (conjugate of z)*w=2+3x+(2x-3)i and (conjugate of w)*z=2+3x-(2x-3)i Find x when you know this :[(conjugate of z)*w-(conjugate of w)*z]/(2*i)=5*[(conjugate of z)*w+(conjugate of w)*z]/2

    now when you say (conjugate of z)*w you mean 2+3x+(2x-3)i correct? so in the actual question you just replace the word with the equation am i getting that correct?

    Start with the right side \[5(2+3x+(2x-3)i)+(2+3x-(2x-3)i)\]/2 \[10+15x+(10x-15)i+10+15x-(10x-15)i\] \[(20+30x)/2\] left side \[2+3x+(2x-3)i-(2+3x-(2x-3)i)\] \[[(2x-3)i+(2x-3)i]/[2i]\] in total we then have \[[(2x-3)i+(2x-3)i]/[2i] = (20+30x)/2\]
