I can solve this problem without that troublesome equation.

First, you draw a line chart, as shown in the figure below. In this way, you only need to find the sum of 36 pots of "jasmine is 36 more than rose" and the remaining 12 pots of orchids. The corresponding score, and then divide the sum by its corresponding score, right?

Second: 36+ 12=48 (pots), accounting for 12.5% of the total. Add up to 25%, and the remaining 1-25%=75% is the corresponding score of 48 pots, divided by 75%=64 (pots).

Third: Rose: 64 times 12.5%=6 (pot)

Jasmine: 6+36=42 (basin)

Orchids: 12 pots

Landlord, please check to make sure it is correct, and everything else is wrong.
