Algebra always makes things sound harder than they actually are, and weird vocabulary can mix up the steps we knew so well.
Part 1: Multiply the first equation by a 2 so that you can cancel out the y variable.
6x - 2y = 0
5x + 2y = 22
Part 2: Actually cancel out the y variables, and combine like terms.
11x = 22
Part 3: Solve for "x" by dividing both sides by 11
x = 2
Part 4: Substitute the variable "x" with the value we just solved for in the original equation.
3(2) - y = 0
6 - y = 0
Then, solve for y by adding y to both sides
6=y
Solution Set = {2,6}

Step-by-step explanation:
so you have to write it all the way and then divide with the denominator then shift the numerator on the other side of the numerator
Answer:
Michael
Step-by-step explanation:
Look at the table below:
The probability of selecting a sale that was made by Quentin is .30, by Michael is .45 and by Bubba is .25.
Since Quentin completes paperwork 90% of the time, he doesn't complete paperwork 10% of the time, following this reasoning we can say that Michael doesn't complete paperwork 20% of the time and Bubba doesn't complete paperwork 15% of the time.
The probability of selecting a file and that it belongs to Quentin AND is incomplete is:
(Probability of selecting a Quentin's file) x (Probability is a Quentin incomplete file) = (0.30)(0.10) = 0.03
Using this same method we have that the probability that it belongs to Michael and is incomplete is (.45)(.20) = 0.09
That it belongs to Bubba and it's incomplete is (0.25)(0.15) = 0.037
The highest of these probabilities is the one that corresponds to Michael: 0.09, therefore he is the most likely culprit.
1000*(1.06)^8. I'm lazy and don't want to type this into a calculator, but what you get out is the answer.
