Fun with Elimination Method: Worksheets & Examples for Solving Equations

The solving systems of linear equations using elimination method is a powerful algebraic technique for solving systems of two linear equations. This method involves strategically eliminating one variable to simplify the problem-solving process. Elimination method examples demonstrate how to align equations, identify coefficients for elimination, and perform addition or subtraction to solve for variables. The process requires careful attention to equation alignment and coefficient manipulation to successfully eliminate variables and find solutions.

• The elimination method involves lining up equations precisely, with x's, y's, and equal signs aligned.
• Coefficients of one set of variables must be the same (positive or negative) for elimination.
• Variables are eliminated by adding or subtracting equations vertically.
• Solutions are found by solving for remaining variables and substituting values.
Elimination method steps include aligning equations, identifying coefficients, eliminating variables, and solving for remaining unknowns.

More Elimination Method Examples

This page continues with additional elimination method examples, demonstrating various scenarios and techniques for solving systems of linear equations.

Example 1: Solve: -9x + 8y = 2 2x + 8y = -20

In this case, the 8y terms can be eliminated by subtracting the equations. The process involves:

  • Subtracting the equations to eliminate 8y
  • Solving for x
  • Substituting x to solve for y

The solution for this system is (-2, -2).

Example 2: Solve: -9x + 8y = 2 2x + 8y = -20 -4y - 6x + 26 = 0 4y = 3x - 19

This more complex example involves multiple equations. The strategy here is to:

  • Choose two equations that allow for easy elimination
  • Solve for one variable
  • Use substitution to find the other variable

Highlight: When dealing with multiple equations, select the pair that allows for the simplest elimination process.

The solution for this system is (5, -1).

Vocabulary: Coefficient - The numerical factor of a term in an algebraic expression.

These examples demonstrate the versatility of the elimination method in solving various types of systems of linear equations, from simple two-equation systems to more complex multi-equation problems.

Solving Systems of Linear Equations using Elimination

This page introduces the elimination method for solving systems of linear equations in Algebra 1. The elimination method is an algebraic approach that involves eliminating one variable to simplify the problem-solving process.

Definition: The elimination method is a technique for solving systems of two linear equations by adding or subtracting the equations to eliminate one variable.

Key requirements for using the elimination method include:

  1. Equations must be precisely lined up, with x's aligned with x's, y's with y's, and equal signs with equal signs.
  2. Coefficients of one set of variables must be the same (positive or negative doesn't matter).

Example: Properly aligned equations: 3x + 2y = 7 -4x + y = -1

Example: Improperly aligned equations: y = 1 5x + 4y = 7

The page provides step-by-step elimination method examples to illustrate the process:

  1. Solve: 3x - 2y = -8 -3x + 4y = 10

In this example, the 3x terms can be eliminated by adding the equations. The solution process involves:

  • Adding the equations to eliminate 3x
  • Solving for y
  • Substituting y to solve for x
  • Checking the solution

Highlight: The key to successful elimination is identifying which operation (addition or subtraction) will eliminate a variable.

The final solution for this system is (-2, 1).
