+118654 (7x+yi)+(11i+5)=1+i
7x+yi+10i+4=0
What do you want me to do with this?
yi=-7x-10i-4
I suppose I could make y the subject - not that there is any great reason to do this.
\(y=\frac{-7x-10i-4}{i}\\ y=\frac{-7x-10i-4}{i}\times \frac{i}{i}\\ y=\frac{-7xi-10i*i-4i}{-1}\\ y=7xi-10+4i\\ y=-10+(7x+4)i\\\)
