Answer: There are 40 cards that x have.
Step-by-step explanation:
Since we have given that
X and y have a total of 47 cards, it is expressed as
x and z were to combine their cards they would have 126 combined, it is expressed as
y and z count there cards together and get a total of 93 cards, it is expressed as
So, solving the above three equations we get that
y = 47 - x,
z = 126 - x,
z = 93 - y
Now, we get that
Hence, there are 40 cards that x have.
