Answer

The two numbers are 8 and 3 respectively.

Step-by-step explanation

We are told that the sum of two numbers is 11 and their difference is 5.

We are then told to find the two numbers.

Let the two numbers be x and y respectively.

The sum of the two numbers is 11.

x + y = 11 .......... equation 1

The difference of the two numbers is 5.

x - y = 5 ............ equation 2

Combining the two equations

x + y = 11

x - y = 5

Adding up the two equations give

x + y + x - y = 11 + 5

2x = 16

Divide both sides by 2

(2x/2) = (16/2)

x = 8

If x = 8,

x + y = 11

8 + y = 11

y = 11 - 8 = 3

Hope this Helps!!!
