Question

the sum of two numbers is 72.if one of the number is 6 more than the other.find the numbers

Answer 1

Let one of the numbers be x.
So,other no.=6+x
sum of the numbers=72
x+6+x=72
2x+6=72
2x=72-6
2x=66
x=66/2
x=33

The numbers are 33 and 39.

Answer 2

The two numbers are 33 and 39

Given:

The sum of two numbers is 72

One of the number is 6 more than the other

To find:

Find the numbers

Solution:

Let x and y be the two numbers

One of the number is 6 more than the other

Let's take y is 6 more than y

⇒ y = x + 6  

Therefore, sum of x and x+6 is equals to 73

⇒ x + x + 6 = 72

⇒ 2x = 72 - 6

⇒ 2x = 66

⇒ x = 66/2 = 33

the value of x = 33

Then y = 33 + 6 = 39

Therefore, the two numbers are 33 and 39
