In the equation, z occurs only as and, to begin with, we can therefore treatas unknown.

Divide both sides by 2+i,

EQ1

and calculate the quotient on the right-hand side by multiplying top and bottom by the complex conjugate of the numerator:

EQ2

This means that .

We check that satisfies the original equation:

EQ3
