Question

Find the value of a and b (a - b)+(a+5)i =a+5i​

Answer 1

Answer:

The value if a is 0 and b is 0

Step-by-step explanation:

(a - b)+(a+5)i =a+5i​

Compare real and imaginary of LHS and RHS:

First compare real part:

a - b = a  

b = a - a

b = 0

Now, imaginary part:

a + 5 = 5

a = 5 - 5

a = 0
