If students go boating, if each boat takes six people, two seats will be free; if each boat takes four people, three boats will be short. How many students go boating? How many boats did you hire?

Suppose x ships are chartered. According to the meaning of the title, it is obtained that & nbsp; & nbsp; 6x-2 = 4x + 4 × 3, & nbsp; & nbsp; 6x-2 = 4x + 12-4x, 6x-2-4x = 4x + 12-4x, & nbsp; 2x-2 + 2 = 12 + 2, & nbsp; 2X ／ 2 = 14 ／ 2, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 7, 7 × 6-2, = 42-2. = 40 (people)
