I order you to forgive yourself!
I found an old magic box for kids. I decided to read the manual. All the tricks were big fails accept for one that I thought was pretty clever.
Here are the instructions:
- Choose a random number (X)
- Multiply by 3
- Add 5
- Multiply by 4
- Add X
- Add a random number (Y)
- Subtract 20
Note: It doesn't work with decimal numbers.
If you post your final number, I can tell you what is your X and Y.
(I guess this topic ends when someone figures out the explanation.)

My final number is 170.

X = 10
Y = 40
I may have made a mistake, but I think I got it right.

I'll bite, how about 260?
X = 20
Y = 0
My numbers were x=1 and y= 157
OR
x=13 y=1

I guess this trick is busted...
Let's say X = 5 and Y = 5
5 * 3 = 15
15 + 5 = 20
20 * 4 = 80
80 + 5 = 85
85 + 5 = 90
90 - 20 = 70
Here is the way it was supposed to work:
Choose a random number (X)
Multiply by 3
Add 5
Multiply by 4
Add X
Add a random number (Y)
Subtract 20
[4(3x + 5) + x] + y - 20 = n
y = n + 20 - [4(3x + 5) + x]
y = n + 20 - (12x + 20 + x)
y = n + 20 - (13x + 20)
y = n
+ 20 - 20 - 13x
y = n - 13x
---
This is a planar cartesian linear equation. With known n, it becomes a linear equation.
Therefore, where n is a whole number greater than or equal to two, it is impossible to determine the x and y coordinates.
None.
This, my friend, is why you don't just copypaste tricks from the internet without analyzing them first. Did you think SEN would be impressed by it?
None.

Did you even bother to read the OP?

I got an other trick. I'm not sure if it's much better than the first one... But it's pretty cool (Until the brains come in
).
Choose two numbers. X and Y
Multiply X by 2.
Add 5 to X.
Multiply X by 5.
Add Y to X (Which is now the result of all the previous operations.)
Tell me your results and I should be able to tell you what your X and Y is. (With a bit of work.) (The higher your two numbers, the harder it seems to be but it's still doable.)

Assuming you mean 2x:
10x+25 + y = 135. X = 10, Y = 10?

5y(2x + 5) = n
5y = n/(2x + 5)
y = n/5(2x + 5)
With n = 5
y = 1/(2x + 5)
I hope you see the problem with this.
None.
