For this case we have that by definition, a linear equation is of the form:

The variable (s) involved in the equation always have exponent 1.
Some examples of linear equations are:

Answer:
In a linear equation the variables have exponent 1.

If the first gardener can finish the job in 6 hours, it means that every hour he completes 1/6 of the job.
By the same logic, the second gardener completes 1/7 of the job per hour.
So, if they work together, they complete

of the job per hour.
So, after 42/13 of a hour, they'll complete the job. Since one hour is made of 60 minutes, 42/13 of a hour is

So, it will take them about 194 minutes to finish the job, i.e. about 3 hours and 14 minutes.
