To find the maximum number of cans x that can be added to the organizer, we subtract 6 from both sides of the inequality x + 6 ≤ 18 to get x ≤ 12.
The student's question is about solving an inequality, specifically x + 6 ≤ 18.
To solve for x, we need to isolate it on one side of the inequality.
So, we subtract 6 from both sides of the inequality which gives us x ≤ 12.
Now, we can see that the number of cans x that can be added to the organizer must be less than or equal to 12.
Hence, the correct inequality representing the number of cans possible to add to the organizer is x ≤ 12.
