Question

The difference of two numbers 4 the sum of tow numbers is 18 what are the two numbers

Answer 1

Answer:

The required two numbers are 11 and 7.

Step-by-step explanation:

Given :

The difference of two numbers is 4 and the sum of two numbers is 18.

To find :

the two numbers

Solution :

Let the two numbers be x and y.

(x is the greater one)

The difference of two numbers is 4 :

x - y = 4 -[1]

The sum of two numbers is 18 :

x + y = 18 -[2]

Add both equations 1 and 2 :

x - y + x + y = 4 + 18

 2x = 22

  x = 22/2

  x = 11

The greater number is 11

Substitute in equation [1],

x - y = 4

11 - y = 4

 y = 11 - 4

 y = 7

The other number is 7.

Therefore, the two numbers are 11 and 7.
