Answer:
Hence, we have:
a= 3 and b= 4
Explanation:
It is given that:
A complex number, (a + bi), multiplied by (2 + 3i) and added to -i gives the product of (-11 + 5i) and (1 – i).
i.e.

Since, we know that :

Hence, we have:

i.e. we have:

and

On multiplying equation (1) by 2 and equation (2) by 3 we get:

on putting the value of a into equation (1) we get:
