Simultaneous equations

I have this equation:
A+b =0
A+c = 6

I've been told I can work this out using simultaneous equations but I don't know how to to do this with 3 different unknowns instead of 2. I feel like I am missing some info.
Can anyone help?

You have infinite solutions, A=-b and $A+c=6\Rightarrow c=6-A=6+b$, so the solutions are $(A,b,c)=(-b,b,6+b)$.
