We know that 2 students are in the restroom.
And one less than three times that number of students are absent, which means (3*2) - 1 = 5 students are absent.
We also know that there are four rows with six desks each that are all x full, which means there are 4 * 6 * x = 24x students in the classroom.
The total number of students Carla teaches, including the ones in and out of the classroom, is the sum of the students in the classroom and the absent students: 24x + 2 + 5 = 24x + 7.
We are given that the total number of students is 23, so we can write: 24x + 7 = 23.
Solving for x, we get: 24x = 16.
Dividing both sides by 24, we get: x = 2/3.
The value of x is 2/3.
#### 2
The answer is: 2
