Always follow this rule when solving a system of equations

The video tutorial explains a rule for efficiently solving systems of equations using substitution. The rule suggests using substitution when a variable has a coefficient of 1 or -1. The instructor demonstrates this with an example, showing how to solve for X and Y by substituting values and simplifying equations. The tutorial emphasizes the simplicity and efficiency of this method, especially when variables are already isolated.
