Answer:
The sum of two numbers is 38 and the difference between them is 2. Find the numbers.
Solution :
Let the numbers be x and y.
The sum of two numbers is 38.
Hence, x + y = 38 ..(i)
The difference between them is 2.
x - y = 2 ...(ii)
Adding (i) and (ii) we get 2x = 36
X = 18
and 18 + y = 38
y = 20
