It is already given in the question
that the smallest of the three even integers is = x
Then
The second even integer = x + 2
The largest even integer = x + 4
Then the equation can be written as
x + x + 2 + x + 4 = 36
3x + 6 = 36
3x = 36 - 6
3x = 30
x = 30/3
= 10
From the above deduction, we can easily conclude that the least consecutive integer is 10. I hope that the procedure is clear enough for you to understand.
