Question

solve for a and b
$(a - b) + (a + b)i = a + 5i$
​

Answer 1

Answer:

Step-by-step explanation:

The value of a is 5 and the value of b is 0.

Step-by-step explanation:

Consider the provided equation.

The multiple of "i " is called the Imaginary part of the equation, whereas the rest of the part is real.

In the above equation the multiple of "i " is (a+b) and 5.

Now compare the real part of the equation with the real part and compare the imaginary part with imaginary.

......(1) and  ......(2)

Solve equation 1 as:  

Now substitute the value of b in equation 2.

Hence, the value of a is 5 and the value of b is 0.
