Hello!
If x² equals 1/100, then x equals 1/10 or -1/10.
I hope it helps!
The expected value is to get either a $5 bill or a $10 bill because of it has more of it's kind in the wallet.
Substitute first Y for the second Y
So it would be x + x + 6 = -2
Then it would be 2x +6 = -2
Move the 6 over so it would be 2x =-8
Divide by 2 your answer is x = -4
