Question 1111074: Please help me to solve: We can fill a certain barrel with water if we use water from 6 small pitchers, 3 medium pitchers and one large pitcher, or from 2 small pitchers, 1 medium pitcher and 3 large pitchers. If we use only large pitchers of water, how many of them do we need to fill the barrel?

6S+3M+1L
2S+1M+3L
The difference in 2L from the first to the second is 4S and 2M
Therefore, each L=2S+M
Need 4L, because 3L+2S+M=4L and 1L+3(2S+M)=4L
