Example
2a+2b+2c=0
3a+b+2c=0
a+b+c=W

I want to get all my variables in terms of W. The type of problem im solving is a statics problem and im asked to find the maximum weight of flowerpot if the chain can hold a max 50lb tension. So W represents the maximum weight (flowerpot) that the system can hold. How do i input this?

There is something about your system that does not sound right to me: 2*a+2*b+2*c=0 --> (a+b+c)=0 then W=0.
Could you please rewrite the exact equations ?
Best,
