Question

The sum of three consecutive integers is 39. What is the least integer?

Answer 1

`x + x+1 + x+2 = 39` where x is the number.

`= 3x+3 = 39`

`= 3x+3=3 = 39-3` Isolate x

`=3x = 36`

`=3x/3 = 36/3` DIvide for x

`x = 12`

Therefore, the smallest number is 12.

Answer 2

12 + 13 + 14 = 39

So least integer = 12
