I'm stuck with this problem:
After one tracter worked 6 hours on a field, another joined. Together they cleared the field in 4 hours. In how many hours can each tractor clear the field by itself, if it's known, that the first one will need 3 hours more than the second.
Any ideas?
P.S. the solve can't be a system of 2 equations with 2 variables, it must be a single one with one variable
