elimination method!!!

Front

What is the elimination method in solving systems of equations?

Back

The elimination method is a technique used to solve systems of linear equations by eliminating one variable, allowing for the solution of the other variable.

What is the first step in the elimination method?

Back

The first step is to manipulate the equations (by multiplying or adding) to align the coefficients of one variable so that it can be eliminated.

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, making it easier to solve for the other variable.

What is the significance of aligning coefficients in the elimination method?

Back

Aligning coefficients allows for the direct cancellation of one variable when the equations are added or subtracted.

How can you determine which variable to eliminate in a system of equations?

Back

Choose the variable that has the same or easily manipulable coefficients in both equations.
