Answer:

Step-by-step explanation:
We have to find the quotient of the division of complex numbers
.
Now, we have to get the expression in simplified form.
=
{Rationalizing the denominator}
= 
=
{Since, i = √(- 1) i.e. square root of negative one, hence, i² = - 1}
= 
=
(Answer)
The total = 3.5 * 4 = 14
(14 + x) / 5 = 4
14 + x = 20
x = 6
