Question

three consecutive integer add up to 51 .what are these integers ?

Answer 1

3x+3=51.
3x=48.
x=16.
Therefore, the first integer is 16 and the next two integers are 17 and18.

Answer 2

let the three integers be x , x + 1 , x + 2

ATQ

x + x + 1 + x + 2 = 51

3x + 3 = 51

3(x + 1) = 51

x + 1 = 51/3

x + 1 = 17

x = 16

now

x + 1 = 16 + 1 = 17

x + 2 = 16 + 2 = 18

the integers are 16 , 17 , 18
