The sum of three numbers is 14. The sum of twice the first number, 4 times the second number, and 5 times the third number is 46. The difference between 7 times the first number and the second number is 46. What are the three numbers?

What color is your favorite number?

I hate everything about this post. Even your icon is laughing at my confusion.

X = H2SeO4

So:
46=2x+4y+5Z
x+y+z=14
7x-y=46

Therefore:
y=7x-46
and
z=14-x-y


Substituting, we get:
46=2x+4(7x-46)+5(14-x-(7x-46))

and we can now solve for x, and from there easily figure out what y and z are. Unfortunately, at this point I need to pull out my calculator, and I am a lazy fuck. Soooooooo this is as far as I go.

Do I win a prize? Will you record the greeting on my voice mail or something?

7, 3, 4.

We have:
x+y+z=14
2x+4y+5z=46
7x-y=46
Easily done with straight substitution.

No infinite solutions, no calculator needed, I'm disappointed!

Yeah, it is a simple equation just overwhelming if you read and expect to solve it immediately in your head. I am sure some people can do that but I suspect most would just get annoyed and give up immediately.
