Discussion Overview

The discussion revolves around solving a system of equations involving the variables x, y, z, and a parameter referred to as "Any." Participants explore the implications of treating "Any" as a variable that can take on different values, particularly zero, and the resulting effects on the linearity of the equations.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant presents a system of equations and seeks assistance in solving for x, y, z, and Any.
  • Another participant suggests temporarily setting Any to zero, framing the problem as a system of linear equations.
  • A different participant argues that the equations are non-linear, prompting a debate about the nature of the equations.
  • Some participants assert that the equations are linear, while others express confusion about arriving at zero for the variables when substituting values.
  • One participant provides a detailed simplification of the equations, leading to a new set of equations but still arrives at zero for x, y, and z.
  • A later reply proposes substituting K for 332Any instead of setting it to zero, suggesting a different approach to the problem.

Areas of Agreement / Disagreement

Participants do not reach a consensus on whether the equations are linear or non-linear. There is also disagreement on the correct approach to solving the equations, particularly regarding the treatment of the variable "Any."

Contextual Notes

Some participants express uncertainty about the implications of setting "Any" to zero and how it affects the overall solution of the equations. There are unresolved mathematical steps in the simplifications presented.

Who May Find This Useful

This discussion may be of interest to those studying systems of equations, particularly in the context of linear algebra and mathematical modeling.

329x / (329x + 276y + 340z + 332Any) =0.5

276y / (329x + 276y + 340z + 332Any) =0.1

340z / (329x + 276y + 340z + 332Any) =0.2

We need to figure x,y,z and Any value. "Any" don't have any equation, so it can be any value.

Anyone can help me how to solve the above problem?

Thanks

Re: How to solve this rquation

Don't worry about the Any, for the moment take Any to be zero. Then you have 3 linear equations in 3 variables and I presume that you are studying solving systems of linear equations.

It is non linear equation
 
Re: How to solve this rquation

It looks linear to me. Why do you think that it is non-linear?

Sorry it is linear equation only, But when i convert all the variables are coming as zero. Plz advice what i am doing wrong.

I consider Any as zero. So I am ignoring the same from the above equation.

If I simply the equation I will get following result
equation 1
329x / (329x + 276y + 340z) =0.5
329x=0.5 * (329x + 276y + 340z)
329x=164.5x + 138y + 170z
329x-164.5x-138y-170z=0
164.5x-138y-170z=0

equation 2
276y / (329x + 276y + 340z) =0.1
276y= 32.9x+27.6y+34.0z
-32.9x+248.4y-34.0z=0

equation 3
340z / (329x + 276y + 340z) =0.2
340z=65.8x+55.2y+68z
-65.8x-55.2y+272z=0

After simplify the 3 equation i will get 3 equations as follow
164.5x-138y-170z=0
-32.9x+248.4y-34.0z=0
-65.8x-55.2y+272z=0

Now x,y,z value is zero It will solve the above 3 equations. But If i set the values as zero in the actual equation it will not solve

329x / (329x + 276y + 340z) =0.5
276y / (329x + 276y + 340z) =0.1
340z / (329x + 276y + 340z) =0.2

So I am sure i have made some mistake. Please advice me.

Thanks

Re: How to solve this rquation

So you can solve the given system of equations? I have. What is the answer?

Are you saying that you want to design an algorithm to solve any system of linear equations? You can do this by manipulating matrices.

Instead of setting Any to zero, perform a substitution. Substitute K for 332Any.

for x, the answer is x = -45K/10*329
