Change x to y, and y to x.
solve for y:
Your answer is:
24/52 because there are 6 even number in a 13 card section
2,4,6,8,10,12
and there are four of them so you multiply 6 by 4 to get 24
since you know there are 52 cards then you will place 24 over 52
you can simplify this fraction to 6/13 depending what you want
You need to solve 5 equations
1. 7x - 2.1 = 14.1
2. 7x - 2.1 = 30.9 and so on
1. 7x - 2.1 = 14.1
7x = 16.2
x = 2.314 so first number in the domain is 2.314
You can calculate the other 4 in the same way
