Answer:

The first group needs 8 boats, the second needs 6

Explanation:

1: x = 8, divide both sides of the equal sign by 5 and you get x = 7.2

2: 8, 5 goes into 36 7 times evenly with a single person remaining and they would need the 8th boat

3: 4x = 24, divide both sides of the equal sign by 4 and you get x = 6

4: the first group
