Full Version: Maths riddle, try to solve
You're currently viewing a stripped down version of our content. View the full version with proper formatting.
okay guys, I want to know if there's any solution to this riddle.

X + Y = Z
Z + X = A
Z = 9,841

I want one concrete solution (so only 1 solution is correct).
My thougts (Click to View)
I simpely, dont get it.

I bet it's actually easy to understand and solve with some algebra, but I'm not in the mood right now Tongue
9 + 0.841 = 9.841
9.841 + 9 = 18.841

X=9
Y=0.841
Z=9.841

However, X and Y could be any two numbers that add up to 9.841. For example:

5 + 4.841 = 9.841
9.841 + 5 = 14.841

X= 5
Y= 4.841

So I don't see how there can be one solution to this problem.
Geek.
Nevermind did something wrong.
I think there was a condition in the original equation which hasn't been mentioned, such as y=z
Afaik this is a undetermined linear system of equations, so you have to guess a bit.

x+y=z
z+x=a -> Z=a-x

=> "a= 9,841+x" and "y=9,841-x"

Trying it with x=1
a=10.841
y=8,841

x+y=z -> 8,841-1 = 9,841
z+x=a -> 9,841+1 = 10.841

ye
its not possible to solve 3 unknown values with only 2 equations. youll need at least as much equations as unknown values.

Nah you end up with an unlimited amount of solutions as michi already wrote.
ye sure if you apply the mathematical principle "guessing" Tongue

i was talking about an explicit solution Smile
Im unsubcribing to this thread.

I dont get anything of this... Oh my "Vincent".

Ye Tongue

The stuff i remember slowly is that a linear system of equations can have 3 solutions.
1. no solution
2. exactly one solution
3. infinite amount of solutions
This thread makes less sense than pauls signature.
Street just completed the bullcrap of this thread Tongue
It's called maths, not bullcrap Wink

As above, there's an infinite range of values for X and Y (you can use -10000 and 10009.841).

yes, a linear view of the world would be nice. but theres so much crazy shit in math its unreal. If youre interested: google for the solution for the squareroot of a negative number for a little entry Wink

Biggrin That made me laugh.
