The first equation can be obtained from the total number of medical equipment received in Shanxi (or Inner Mongolia)
The second equation is obtained according to the total cost is 7600 yuan.
Here are the detailed steps:
Solution: Let the number of medical equipment shipped from Shanghai to Shanxi be X, then the number of units shipped to Inner Mongolia is (10-X),
The number of medical equipment shipped from Beijing to Shanxi is Y, then the number of units shipped from Beijing to Inner Mongolia is (4-Y).
Based on the meaning of the question, we have: X+Y=8
400X+(10-X)800+300Y+(4-Y)500=7600
Solve this system of equations to get: X=4, Y=4
That is, Shanghai shipped 4 medical equipment to Shanxi, and 6 to Inner Mongolia;
Beijing shipped 4 medical equipment to Shanxi, and 6 to Inner Mongolia;
Beijing shipped 4 medical equipment to Shanxi, and 6 to Inner Mongolia. equipment shipped from Beijing to Shanxi is 4 units, and the shipment to Inner Mongolia is 0 units.
The answer is complete. (I hope my answer can help you, if you have any questions welcome to add the follow-up questions
