Answer:

The two numbers are 8 and 4

Step-by-step explanation:

Given,

The sum of two numbers = 12

Their difference = 4

To find,

The numbers

Solution:

Let x and y be the two numbers,

Since the sum of the two numbers is 12, we have

x+y = 12 ----------------(1)

Since the difference between the two numbers is 4, we have

x -y = 4 ------------(2)

Adding equations(1) and (2) we get,

2x = 16

x = 8

Substituting the value of x in equation (1) we get,

8+y = 12

y = 4

Hence the two numbers are 8 and 4
