Cracking the Code: Using Substitution to Solve Systems of Linear Equations - em

Substitution is a method used to solve systems of linear equations by replacing one variable with an expression involving the other variables. The process involves isolating one variable in one equation and substituting it into the other equation to solve for the remaining variable. This technique allows individuals to simplify complex equations and arrive at a solution.
