Please let me know if that's wrong.
These are two lines in point slope form. They'll meet at some x that makes the ys equal.
is the only solution.
Exactly one solution.
We really only had to ensure the lines had two different slopes. Then there's always exactly one solution.
If the lines had the same slope, they're either the same line (coincident) so an infinite number of solutions, all the points on that line, or they're parallel, no solutions.

Let's write the total of gallons in improper fraction:
Step 1: Multiply the denominator by the whole number
6 × 5 = 30
Step 2: Add the answer from Step 1 to the numerator
30 + 1 = 31
Step 3: Write answer from Step 2 over the denominator
5 1/6 = 31 / 6
Let's divide the total gallons by what she used each hour to get the number of hours:
Let convert the improper fraction to mixed number:
93/10 = 9 3/10
<h2>She was driven a total of 9 3/10 hours</h2>
