Contact [7]

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+y=47

x and z were to combine their cards they would have 126 combined, it is expressed as

x+z=126

y and z count there cards together and get a total of 93 cards, it is expressed as

y+z=93

So, solving the above three equations we get that

y = 47 - x,

z = 126 - x,

z = 93 - y

Now, we get that x=40,y=7,z=86

Hence, there are 40 cards that x have.
