Set up the following equations:
x is the amount of hours worked on the weekday job, and y is the amount of hours worked on the weekend job.
We'll use substitution to remove one of the variables.
Multiply the first equation by -18 to get opposite coefficients for y:
Combine these two equations together:
Divide both sides by 2 to get x by itself:
Plug in x to the first original equation:
Subtract 25 from both sides to get y by itself:
