The sum of two numbers is 71. Their difference is 7. Find the numbers.

Answer 1

Let first number be x, therefore second number = 71-x

According to question

Difference of two number = 7

Or, first number - second number = 7

0r, x-(71-x)= 7

Or, x-71+x= 7

0r, 2x-71=7

0r, 2x= 78

0r, x= 39

Hence first number =x= 39

Second number = 71-x= 71-39= 32 Ans.
