The class of 42 students went to the garden boating, a total of 8 boats, 6 people for each big boat, 4 people for each small boat

The class of 42 students went to the garden boating, a total of 8 boats, 6 people for each big boat, 4 people for each small boat

If x large vessels are rented, there will be 8-x small vessels
6X+4(8-X)=42
2X=10
X=5
There are 5 big boats and 3 small boats

Forty two people in the class went to the park to row boats. They rented a total of 10 boats, 5 for each big boat and 3 for each small boat

If you rent a boat, you can only take 3 * 10 = 30 people, which is 42-30 = 12 people less than 42 people. Therefore, there are 12 / (5-3) = 6 big boats, and 10-6 = 4 small boats. You can't ask

56 students went boating in the park and filled up the three big boats and seven small boats. It is known that each big boat can take two more students than each small boat. How many people can each big boat and small boat take?

Let each ship take x persons, 3x + 7 × (X-2) = 56, & nbsp; & nbsp; & nbsp; & nbsp; 3x + 7x-14 = 56, & nbsp; & nbsp; & nbsp; & nbsp; 10x-14 + 14 = 56 + 14, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 10x △ 10 = 70 △ 10, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp
