Arithmetic method:

Assuming that everyone takes a big boat, a * * can take 6× 10=60 (people).

Actually do 46 people, do 60-46 less =14 (people).

Then 14/(6-4)=7 ships.

Ship has 10-7=3 (pieces).

A: I rented three big boats and seven small boats.

Equation method:

If X big ships are chartered, then according to the meaning of the question, there are

6a+4( 10-x)=46

6a+40-4x=46

2x=6

x=3

10-x=7 (strips)
