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

2.

FLASHCARD QUESTION

Front

What does it mean if a system of equations has infinite solutions?

Back

A system has infinite solutions when the equations represent the same line, meaning every point on the line is a solution.

3.

FLASHCARD QUESTION

What does it mean if a system of equations has no solution?

Back

A system has no solution when the equations represent parallel lines that never intersect.

4.

FLASHCARD QUESTION

Front

How do you determine if two equations are equivalent?

Back

Two equations are equivalent if they can be transformed into one another through algebraic manipulation, such as multiplying or dividing by a non-zero constant.

5.

FLASHCARD QUESTION

Front

What is the first step in using the elimination method?

Back

The first step is to align the equations and manipulate them (if necessary) so that the coefficients of one variable are opposites.

6.

FLASHCARD QUESTION

Front

How can you manipulate equations to prepare for elimination?

Back

You can multiply one or both equations by a constant to make the coefficients of one variable opposites.

7.

FLASHCARD QUESTION

Front

What is the solution to the system: 4x + 4y = 10 and 4x + 4y = 10?

Back

The solution is infinite solutions, as both equations are identical.
