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).
tbh I think there is an infinite amount of possible solutions, am I right?
I simpely, dont get it.
Is it me, or am I just so dumb as shit ?
I bet it's actually easy to understand and solve with some algebra, but I'm not in the mood right now
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.
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"
i was talking about an explicit solution
Im unsubcribing to this thread.
I dont get anything of this... Oh my "Vincent".
Boohoo, was that so important to open this spoiler and read this nonsense ?

Ye
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
It's called maths, not bullcrap
As above, there's an infinite range of values for X and Y (you can use -10000 and 10009.841).

That made me laugh.
