The first equation can be derived from the total number of medical equipment received in Shanxi (or Inner Mongolia).
The second equation is based on the total cost of 7600 yuan.
The following are the detailed steps:
Solution: If the number of medical equipment shipped from Shanghai to Shanxi is X, the number of medical equipment shipped to Inner Mongolia is (10-X).
The number of medical equipment transported from Beijing to Shanxi is y, so the number of medical equipment transported from Beijing to Inner Mongolia is (4-Y).
According to the meaning of the question, there are: X+Y=8
400 X+( 10-X)800+300Y+(4-Y)500 = 7600
Solve this system of equations, X=4, Y=4.
That is, there are 4 medical equipment shipped from Shanghai to Shanxi and 6 to Inner Mongolia.
Beijing sent 4 sets of medical equipment to Shanxi and 0 sets to Inner Mongolia.
