FLASHCARD QUESTION

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.

2.

FLASHCARD QUESTION

Front

What do you need to multiply the top equation by to create a zero pair?

Back

You need to multiply the top equation by a value that will make the coefficients of one of the variables equal and opposite in the two equations.

FLASHCARD QUESTION

Front

If you multiply the equation 2x + 3y = 12 by -2, what is the new equation?

Back

-4x - 6y = -24.

4.

FLASHCARD QUESTION

Front

In the elimination method, which variable do you typically aim to eliminate first?

Back

You typically aim to eliminate either the x or y variable, depending on which is easier based on the coefficients.

5.

FLASHCARD QUESTION

Front

What does it mean to create a zero pair in elimination?

Back

Creating a zero pair means adjusting the equations so that when added together, one variable cancels out to equal zero.

6.

FLASHCARD QUESTION

Front

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

Back

You look for the variable with coefficients that can easily be manipulated to create a zero pair.

7.

FLASHCARD QUESTION

Front

What is the first step in solving a system of equations using elimination?

Back

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