That is very cool and rare if you did it nice job!
Add, -11.5x and move it over to 8.5x
Then, subtract them together and you get 20x + 51.86 = 51.76
And you move (subtract) 51. 86 over to 51.76, subtract that and you get 20x = -0.1
Divide, and your answer is -200
I believe the answer is 3 minutes
At the 3 minute mark, Maxine will be half way done and Sammie will still have 6 minutes left to mow the grass
