Documenting Substitution Steps for Account Reconciliation

In a professional audit, an analyst uses the system of equations {x+y=1,y=x+5}\{x + y = -1, y = x + 5\} to determine necessary adjustments for two accounts, xx and yy. Describe the specific procedure for solving this system using the substitution method. In your response, you must identify the exact algebraic expression from the second equation that is substituted into the first, and recall the specific reason why the standard first step of 'isolating a variable' is considered already complete for this system.
