Original question: There are a batch of peaches. Type A can hold 12 boxes, and Type B can hold 15 boxes. Each box of Type A is 3 kilograms more than that of Type B. How many kilograms are these peaches?

* is the symbol of multiplication,/is the symbol of division.

Answer:

Solution: If each B box can hold X kilograms, then each A box can hold (X+3) kilograms.

12*(X+3)= 15X

36+ 12X= 15X

36= 15X- 12X

3X=36

X= 12

(X+3)= 15

15X= 180

A: This batch of peaches * * *180kg.
