Sub the x and y values into the equation. The x value is the first number in the coordinate, and the y value is the second number.
If the left side is equal to the right side, it is a solution.
Example:
4x-5y=24
4(-9)-5(-12)=24
-36+60=24
24=24
Remember: if the left side does not equal the right side, it is not a solution.

1 / (2/3) + 1 = 3/2 + 1 = 5/2
=> 5/2 of lawn per hour
