A mathematical problem of linear equation with one variable If you plant 10 saplings per person, there will be 6 saplings left; if you plant 12 saplings per person, there will be 6 saplings missing. How many people plant trees?

A mathematical problem of linear equation with one variable If you plant 10 saplings per person, there will be 6 saplings left; if you plant 12 saplings per person, there will be 6 saplings missing. How many people plant trees?

There are x people planting trees
Then 10x + 6 = 12x-6
The solution is x = 6, there are 66 people
