Question

The sum of two consecutive multiples of 3 is 69. find these.

Answer 1

Let the first consecutive multiple be x

Let the second consecutive multiple be x + 3

Given, the sum of two consecutive multiples of 3 is 69.


According to the question,

x + x + 3 = 69

2x + 3 = 69

2x = 69 - 3

2x = 66

x = $\dfrac{66}{2}$

x = 33



First consecutive multiple => x

=> $\underline{33}$

Second consecutive multiple => x + 3

=> 33 + 3

=> $\underline{36}$

Answer 2

$\huge \red{dear \: friend}$
here is your answer OK ☺☺☺☺☺☺☺

first consecutive number will be represented by X

second consecutive number will be (x + 1 )

if we add both in 2 so 3 (2x + 1 ) .

so we know that 2x+1 = 69

2 x = 68
x = 34

first consecutive number will be 34

second consecutive number will be 34+1=35
