Question

Find two numbers such that one of them exceeds the other by 9 and their sum is 81 ​

Answer 1

Answer:

Convert given word problem into algebraic

equation.

Let first number = x  

Second number = 9 exceeds the first number

Sum of the two numbers = 81

x + ( x + 9 ) = 81

x + x + 9 = 81

2x = 81 - 9

2x = 72

x = 72 / 2

x = 36

Therefore ,

First number = x = 36,

Second number = x + 9 = 36 + 9 = 45
