how many guests were present at a dinner if every two guest shared a bowl of rice, every three guests shared a bowl of broth, every four guests shared a bowl of fow, and 65 bowls were used together.

x/2+x/3+x/4=65
multliply both sides by 12
6x+4x+3x=65*12
13x=.... 
60 guest were present at dinner. Is this correct?
