Solving Systems - Elimination Method (GREEN)

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.

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 if a system of equations has no solution?

Back

It means that the lines represented by the equations are parallel and never intersect.

What is a consistent system of equations?

Back

A consistent system has at least one solution, meaning the lines intersect at one or more points.
