To solve this system, we just need to multiply the first equation by -1, and then sum those equations.
Then, we use this value to find the other one
As you can observe, the system of equations have a unique solution.
Therefore, the answer is one solution.

The order does not matter, so we will be using combinations here. 52C1 is the first one since there is only one possibility. 16C1 is the second. You have to multiply these two, so 52 X 16 = 832.
Since she has seven key the probability that the first one will open the door is
if it takes three attempts to open the door,the probability is
if the three attempts would not work
then the probability that the fourth attempt will open the door is
