One possible equation would be 20 = 1/2x + 4.
Let x be the number of students in his homeroom. 1/2x is half of the students in his homeroom. Four more than 1/2 would be 1/2x + 4. This is, or equals, the 20 students that have tickets.
A. Is your answer, if the games cost the same amount and he bought 3, that would give you 3x, the total is 65, and 14 is what was left. You would subtract 14 from the total, then divide by 3 to get x by itself.
The answer is x is less than 1.
Firs find the prime factors:-
12 = 2*2*3
24 = 2*2*2*3
30 = 2*3*5
Picking out the common factors from all three we get
2*3 = 6
Answer is 6.
