xenn [34]
It will take 24 days for them to exercise together. You have to find a common number that both 8 and 12 go into evenly so 8x1=8, 8x2=16, 8x3=24 and 12x1=12, 12x2=24. So this will be Drew's third time at the gym and Sara's second time when they both go together

If the slopes are the same but the y-intercepts are different, the system has no solution.

If the slopes are different, the system has one solution.

If the slopes are the same and the y-intercepts are the same, the system has infinitely many solutions.
