Solving by Elimination - Addition

Front

What is the Elimination Method in solving systems of equations?

Back

The Elimination Method is a technique used to solve systems of equations by eliminating one variable, allowing for the other variable to be solved directly.

Front

What is the first step in using the Elimination Method?

Back

The first step is to manipulate the equations so that when added or subtracted, one of the variables cancels out.

What does it mean to 'combine' equations in the Elimination Method?

Back

Combining equations involves adding or subtracting the equations to eliminate one variable.
