Terry has $2.35 in nickels and dimes. If he has a total of thirty two coins, how many of each type of coin does he have?
Before answering to this question we must know the following conversions.
1 dollar = 100 cents 1 dime = 10 cents 1 nickel = 5 cents.
Let the number dimes be x, then the number of nickels is .
Therefore, The value of x dimes is $0.10x and, The value of nickels is $0.05 ( ).
We have been given that the total amount Terry has with him is $2.35.
Therefore, 

So, the number of dimes is 15 and the number of nickels is 17.

Find the real values of x and y:

Given, 
Two complex numbers are said to be equal if the corresponding real parts are equal and the corresponding imaginary parts are equal.
So, 
Compare the real and imaginary parts on both sides, then we get,
..... (1)
And 
...... (2)
2 x (2) ....... (3)
(3) - (1) 
From (1), we get
