Answer:
-17x=234
Step-by-step explanation:
Given that:
![\dfrac{2x}{3}-\dfrac{5x}{9}-\dfrac{x}{6}-\dfrac{5x}{12}=\dfrac{13}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B2x%7D%7B3%7D-%5Cdfrac%7B5x%7D%7B9%7D-%5Cdfrac%7Bx%7D%7B6%7D-%5Cdfrac%7B5x%7D%7B12%7D%3D%5Cdfrac%7B13%7D%7B2%7D)
![\dfrac{72x-60x -18x-45x }{108} = \dfrac{13}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B72x-60x%20-18x-45x%20%7D%7B108%7D%20%3D%20%5Cdfrac%7B13%7D%7B2%7D)
![\dfrac{-51x }{108} = \dfrac{13}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B-51x%20%7D%7B108%7D%20%3D%20%5Cdfrac%7B13%7D%7B2%7D)
![-102x = 1404](https://tex.z-dn.net/?f=-102x%20%3D%20%20%20%201404)
![-\dfrac{102x}{6} = \dfrac{1404}{6}](https://tex.z-dn.net/?f=-%5Cdfrac%7B102x%7D%7B6%7D%20%3D%20%5Cdfrac%7B1404%7D%7B6%7D)
-17x = 234
Answer:
Total possible number of outcomes = C(24,6) [24 choose 6]
=24!/(6!18!)
= 134596
Out of which there is only one winning combination.
Therefore we conclude:
P(win 20000)=1/134596
P(lose 1)=134595/134596
and hence the expected value is:
20000*(1/134596)+(-1)*(134595/134596)
=-114595/134596
=-0.8514 (rounded to four places after decimal)

Answer: The last line is a mistake
Step-by-step explanation: because you are not supposed to combine something that has a term and something that doesn't. So it should just stay has 40g+24
