problem

Let a,ba, b, and cc be real numbers. Consider the system of simultaneous equations in variables xx and y:y: ax+by=c−1a x+b y =c-1 and (a+5)x+(b+3)y=c+1(a+5) x+(b+3) y =c+1. Determine the value(s) of cc in terms of aa such that the system always has a solution for any aa and bb.

Original LaTeX notation
Let $a, b$, and $c$ be real numbers. Consider the system of simultaneous equations in variables $x$ and $y:$ $a x+b y =c-1$ and $(a+5) x+(b+3) y =c+1$. Determine the value(s) of $c$ in terms of $a$ such that the system always has a solution for any $a$ and $b$.
