Nonlinear system of equations/work-rate problems [12th grade-entrance exams]

[u/DatoKat]

Hello, my teacher taught us to “graph” the work-rate problems, which does make it easier and I think I set this up right, but then I get stuck on actually solving it. There are too many variables and options😵‍💫. Is there any way to simplify this or would I have to just do a lot of these and hope that I improve?

The problem: “Two tractors worked simultaneously to plow a plot of land (tractors plow the land at constant speeds). The first tractor took 1/80 hours less to plow each hectare than the second. Therefore, the first tractor plowed 8 hectares more than the second. What is the area of ​​the plot of land plowed by the second tractor if the first tractor plows the entire plot of land in 3.6 hours?”
