## Two Equations, Two Unknowns - II

Summary
The lesson focuses on the elimination method as a strategy for solving systems of equations, highlighting its advantages over substitution, especially in more complex scenarios.
• Elimination is preferred when coefficients of the same variable across two equations are equal, opposite, or multiples of each other.
• The method involves choosing a variable to eliminate, then multiplying equations to align coefficients for cancellation.
• Solving systems with elimination can be more straightforward and less cumbersome than substitution, avoiding the introduction of fractions.
• Strategic multiplication of equations allows for the elimination of one variable, simplifying the system to a single variable equation.
• In cases where the goal is to find the value of an expression rather than individual variables, elimination can offer a more direct path.
