## Two Equations, Two Unknowns - II

Summary

The content provides an in-depth exploration of 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 dealing with equations where coefficients are not +1 or -1, as it avoids unnecessary complexity introduced by fractions.
- The method involves adding or subtracting equations to eliminate one variable, allowing for the straightforward solving of the remaining variable.
- Multiplying equations by certain factors can align coefficients to facilitate the elimination of a chosen variable.
- Choosing which variable to eliminate depends on the coefficients' relationship, with the goal of simplifying the equations as much as possible.
- In some cases, solving for an expression's value directly is more efficient than finding individual variable values, indicating a strategic approach to problem-solving.
