It’s definitely-20
Add 9 to both sides to cancel it out so it is now
4x-20=5x
Than subtract 4x on both sides it is now
-20=x
Because 5-4 equals 1 and 1x is just written as x

wait i am kinda counfues help anyone?
This is best done using a Venn Diagram.
Given:
Probability that he gets into NYPD is 0.60
Probability that he gets into CSI is 0.70
Probability that he gets into both is 0.40
Probability that he gets into ONLY NYPD? 0.60 - 0.40 = 0.20
Probability that he gets into ONLY CSI? 0.70 - 0.40 = 0.30
The expected value of the outcome of the bid is $0.18
So let's start by counting how many bids are placed up to a total of 160.
100*160 = 16000.
What will be your arbitrary bid? As each bid has an equal chance of success, the average of all bids is used. (One cent plus 160 dollars) / 2 = 80 dollars (rounded)
Your odds of winning are 1/16000 (1 bid out of 16000).
If you win, your profit is 1920 ($2000 minus $80.00).
1920/16000 is $0.12
Your cost to enter the auction is $1, and your average winning offer is $0.12.
The result is $0.18 (0.12-1=-0.88).
Thus the expected value of the outcome of the bid is $0.18
