To find a unit rate, we divide the quantity of cords of wood by the time.
This gives us the complex fraction.

This is the same as

To divide two fractions, we multiply by the reciprocal of the second fraction.


This simplifies to:

The unit rate is 1.5 cords per hour
Isolate the variable by dividing each side by factors that don’t contain variable.
Answer: x = -2
