Equation:
sum - 2(x-2) = 16
4x-2 - 2x+4 = 16
2x + 2 = 16
x = 7

Let the first integer be F
Then other three are: F + 1, F + 2, and F + 3
Since twice the first subtracted from the sum of the other three integers equals 16, we therefore have: (F + 1 + F + 2 + F + 3) - 2F = 16
3F + 6 - 2F = 16
F + 6 = 16
F, or first integer = 16 - 6, or 10
The four integers are:

Check
========
2 times first = 2(10), or 20
Sum of other three = 11 + 12 + 13, or 36
36 - 20 = 16 (TRUE)
