Answer:
201.5x-y=-6
Step-by-step explanation:
−6x−2y=−1618x+6y=48
Collect like terms
-6x+1618x-2y-6y=-48
1612x-8y=-48
Divide through by 8
1612x/8-8y/8=-48/8
201.5x-y=-6
Hey there!
We can set this up a proportion to figure out the percent we need.

Therefore, the probability if observing at least one mistake made by this professor is 20%.
I hope this helps!
