Question

The sum of three consecutive even number is 30. Find the number

Answer 1

Answer:

9,10,11

Step-by-step explanation:

let the three consecutive number be x,x+1,x+2

now according to question

x+x+1+x+2=30

3x+3=30

3x=27

x=9

therefore numbers are 9,10,11.

Answer 2

Answer:

9, 10, 11

Step-by-step explanation:

x + x+1 + x+2 = 30

3x + 3 = 30

3x = 30 - 3  (transpose)

3x = 27

x = 27/3    (transpose)

x = 9

thus the numbers are:- x , x+1 , x+2

= 9, 9+1 , 9+2

= 9, 10 ,11
