What is the value of (–7 3i) – (2 – 6i)? –9 9i –9 – 3i –5 – 3i –5 9i

Value of

Step-by-step explanation:

To find the value of the give expression:

Property of subtraction of complex number states that the subtract  of two complex numbers and  is defined as the complex number  i.e  

It is observed that while subtracting two complex numbers the real and imaginary parts of the system is obtained by subtracting the real and imaginary parts of the summands.

Now;

Therefore, the value of is, -9 + 9i.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

b
