Answer: The first number is a = 12 and the second number is b = 9.
Step-by-step explanation: Given that the first number a and second number b is related to each other by the following system of equations :
We are to find the first and second number, i.e., a and b.
From equation (i), we have
Substituting the value of a from equation (iii) in equation (ii), we get
Putting the value of b in equation (iii) we get
Thus, the first number is a = 12 and the second number is b = 9.
