Define the elimination method in solving systems of equations.

Back

The elimination method involves adding or subtracting equations to eliminate one variable, making it easier to solve for the other variable.

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables.

Front

What does it mean to eliminate a variable in a system of equations?

Back

To eliminate a variable means to manipulate the equations so that one variable is removed, allowing for easier solving of the remaining variable.

Front

What is the first step in using the elimination method?

Back

The first step is to align the equations and determine which variable to eliminate.
