Question

if 3+xi=(x+1)+2i what is the value of x?

Answer 1

compare the terms first and then simplify for `x`

Answer 2

like in this one,
\[\large \bf \mathbb{R}~part=\mathbb{R}~part\]
and \[\large \bf Imaginary~part=Imaginary~part\]

Answer 3

so, we get
\[\large \bf 3=x+1\] (Equating Real part)
\[\large \bf x=2\] (Equating Imaginary part)

Answer 4

hope you understand ! @halghafilee
