1.2x=7.2

x=6

A: The apprentice weaves 6 meters per hour.

The third problem has been solved: A bag of rice weighs X kilograms, and B bag of rice weighs (x-4.6×2) kilograms.

x+(x- 4.6×2)=68

2x-9.2=68

2x=68+9.2

2x=77.2

x=38.6

So x- 4.6×2=38.6-4.6×2.

x- 4.6×2=38.6-9.2

x- 4.6×2=29.4

Answer: A bag of rice weighs 38.6 kg, and B bag of rice weighs 29.4 kg. Apprentices weave x meters per hour.
