I need help solving for multiple variables. I tried systems of equations, but I wound up stuck.
Here's some of the equations:

3 = Ax + B
7 = Cx + B
6.5 = Hx + B

You have 5 equations and 7 unknowns

#

What are you solving for exactly

#

It's 5 unknowns I'm trying to solve for B

#

The X's are the same, B is also the same across the board

#

Might this be clearer?
3 = Ax + Cx + Hx + B
A = ? ; C = 0 ; H = 0

7 = Ax + Cx + Hx + B
A = 0 ; C = ? ; H = 0

6.5 = Ax + Cx + Hx + B
A = 0 ; C = 0 ; H = ?

#

Or = x(A + C + H) + B

#

And B = ?

#

And x = ?

@fiery crescent you have more unkowns than equations. There will be an infinite set of solutions

#

Or and A, C, and H known variables?

#

What is the original question?

I have several containers, each container weighs the same, each container has a differing amount of the same material, some beads. Since each container has a different amount of stuff, they have different weights with the beads in them. The weight of each container with the beads in them are known, what isn't known is the object of the problem being, the number of beads in each container, the mass per bead, and the weight of the container.

Alright. Not really sure what to do with that and the given information. I don't see what you're trying to solve for in your equations

#

I kinda do, but it looks like info is still missing

Yeah, thanks for your help though

#

I think this one can be closed
