Question

The sum of three consecutive multiples of 7 is 777 . Find the multiples. please do with method

Answer 1

Answer:

Step-by-step explanation:

Let the consecutive multiples be 7x, 7x  +  7, 7x+14

7x+(7x +7) + (7x + 14) = 777

              42+ 3x  = 777

                      3x = 777-42

                      3x = 735

                         x = 735 / 3

                         x = 245

hope its correct

Answer 2

let 1st multiple be x

2nd multiple will be x + 7

3rd multiple will be x + 14

$3x + 21 = 777$

$3x = 777 - 21$

$3x = 756$

$x = \frac{756}{3}$

$x = 252$

Therefore 3 consecutive multiple of 7 are :- 252, 259, 266.
