Answer 2

Question :

The sum of two numbers is 15 and the difference is 11 what are the two numbers ?

Answer :

Let the two numbers be x and y .

Sum of two numbers = 15

x + y = 15 ___ equation 1

Difference of two numbers = 11

x - y = 11 ____equation 2

☆ Add equation 1 and equation 2

x + y + x - y = 15 + 11

2x = 26

x = 13

Put the value of x in equation 1 .

13 + y = 15

y = 15 - 13

y = 2
