Practice with Elimination add/subtract

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 adding or subtracting the equations to eliminate one of the variables.

Front

Which of the following is NOT a method to solve systems?

Back

Distribution

Front

What is a system of equations?

Back

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

Front

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

Back

Get both equations in standard form and line up the like terms.

Front

When using the elimination method, which variable should be eliminated first in the system 5x - y = 12 and 3x + y = 4?

Back

y

Front

What should you do before applying the elimination method?

Back

Make sure that the equations are lined up.

Front

What is the goal of the elimination method?

Back

The goal is to eliminate one variable to make it easier to solve for the other variable.

Front

How can you eliminate a variable in a system of equations?

Back

You can eliminate a variable by adding or subtracting the equations.

Front

What is the standard form of a linear equation?

Back

The standard form of a linear equation is Ax + By = C, where A, B, and C are integers.

Front

What does it mean for equations to be in standard form?

Back

It means that the equations are arranged so that all variables are on one side and constants are on the other.
