Start by recognizing that from the smallest to the largest integer can be written as x, x+1, and x+2.
.
Next you are told that twice the smallest (which twice x or 2x) equals eleven more than the largest which is 11 + (x + 2).
.
Write this out as the equation:
.
2x = 11 + x + 2
.
Subtract x from both sides and you have:
.
x = 11 + 2 = 13
.
This tells us that the smallest seat number is 13. This means that the three seats are numbered 13, 14, and 15.
.
Check to make sure that twice the smallest seat number (13 times 2) is 11 more than the largest seat number (15 + 11). It is, so the answer is correct.
.
Hope this helps you to understand the problem.
