After removing all queens we have 12 types of cards left.
So, total number of unique four card combination will be =
12C1 * 11C1 * 10C1 * 9C1 = 11880, where nCr = n!/ r!* (n-r)!
Equation of 2x-y= 5 where we know the y value from (x,1)
We substitute the y value in the equation to get the x value easily
2x-1= 5
2x = 5 + 1
2x = 6
x = 3 (divide both side by 2)
Answer x = 3 when y = 1
