Answer 1

Answer:

Step-by-step explanation:

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

Hence, the numbers are 18 and 20.
