[ 2x + y = -9 ] x -3
[- 3x +11= y ] x 2
-6x -3y = 27
-6x + 22 = 2y
-6x +27 = 3y
-6x +22 = 2y
5 = y
-6x -3x5 = 27
-6x -15 = 27
-6x = 42
-x = 42/6
-x = 7
x = -7
answer
x = -7
y = 5

The number of ways to deal 5 cards to 5 players from a 52-card deck in a game of poker is (52!)/[(27!)*(5!)^5].
- Permutations and combinations define nCr as ways of selecting 'r' number of items from 'n' items.
- nCr = (n!)/[r!(n-r)!]
- here we want to deal 5 playing cards to each player.once we deal 5 playing cards to any participant,
- the playing cards left inside the deck are reduced through five.
- We deal a total of 25 playing cards, i.e., 5 playing cards to 5 gamers.
- The number of ways to deal five playing cards to the primary participant is 52C5.The number of approaches to deal 5 playing cards to the second one participant is 47C5.
- The wide variety of ways to deal 5 cards to the 0.33 player is 42C5.
- The variety of methods to deal 5 cards to the fourth participant is 37C5.
- The quantity of ways to deal 5 playing cards to the 5th player is 32C5.
- the full quantity of methods is the general multiplication.
- The total number of solutions = 52C5 * 47C5 * 42C5 * 37C5 * 32C5
- When we simplify, we get (52!)/[(27!)*(5!)^5].
