Question

the sum of two consecutive multiples of 5 is 65. find the number

Answer 1

Let the two consecutive multiples of 5 are
5(x + 1) and 5(x + 2)

According to the question,
5(x + 1) + 5(x + 2)= 65
=> 5x + 5 + 5x + 10= 65
=> 10x + 15= 65
=> 10x = 65 - 15
=> 10x = 50
=> x = 50/10
=> x = 5

Therefore, the two numbers are:
5(x + 1)
=5(5 + 1)
=25 + 5
= 30

5(x + 2)
= 5(5 + 2)
=25 + 10
= 35

PROOF: 30 + 35 = 65

Answer 2

The sum of two consecutive multiple of 5 is 5x and 10x
Then, 5x+10x=65
15x=65
X=65 divided into 15
X=13/3
