@hartnn

hartnn (hartnn):

y=7/2

Yeah :D

hartnn (hartnn):

so y= -7/2

OpenStudy (hba):

Thanks.

OpenStudy (hba):

@hartnn I Got stuck in a question \[\frac{ x+yi }{ 2+i }=5-i\]

hartnn (hartnn):

(5-i)(2+i) = x+yi

OpenStudy (hba):

I have solved it till here \[\frac{ 2x-x i+2yi+y }{ 5 }=5-i\]

OpenStudy (hba):

I will try it the way you told,wait @hartnn

OpenStudy (hba):

x=11 and y=3,Right @hartnn

hartnn (hartnn):

yes

OpenStudy (hba):
