Simultaneous Equations: Elimination Methods

🎬 Video Tutorial

  • (0:01) The Elimination Method: Simplifies solving systems of linear equations by removing one variable, making it easier to find the solution.
  • (0:08) Elimination Techniques: Adding or subtracting two equations to eliminate a variable (e.g., $y$) and solve for the other (e.g., $x$)
  • (0:23) Transforming Equations: Sometimes, equations must be multiplied to align terms for elimination. This step is key for cases where direct addition or subtraction won’t eliminate a variable.
  • (1:05) Substitute and Verify: After finding one variable, substitute it back into an original equation to find the other. Always verify solutions by substituting both values back into the original equations.
