The Elimination Method, or Addition Method, is a technique used for solving algebraic equations dealing with constants and variables. This method is typically taught in high school Algebra classes. The technique involves adding or subtracting a constant from both sides of the equation, to isolate the variable and thus solve the equation. For demonstration purposes, the equation x + 8 = 12 will be used. Write the equation down paper: x + 8 = 12. Subtract 8 from each side of the equation to isolate the variable, x. The equation will now look like: x + 8 – 8 = 12 – 8. Solve each side of the equation: x + 8 – 8 = x. 12 – 8 = 4. Rewrite the deduced equation to articulate the value of x: x equals the value of 12 minus 8. x = 4.
