Alg 1A Elimination practice

Front

What is the solution to the system? (1) 2x + 2y = -2 (2) 3x - 2y = 12

Back

(1, 3)

Front

What is the first step in finding the solution using elimination for the system? (1) 2x + 2y = -2 (2) 3x - 2y = 12

Back

Add the like terms. The y terms will cancel out.

Front

Back

Elimination because there are no variables by themselves.

Front

What is the solution to the system? (1) 3x + y = 19 (2) 2x - y = 6

Back

(5, 4)

Front

What does elimination mean in the context of solving systems of equations?

Back

Elimination is a method for solving systems of equations by removing one variable, allowing for the other variable to be solved.

Front

What is a system of equations?

Back

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

Front

What is the goal when using the elimination method?

Back

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

Front

What is the elimination method used for?

Back

The elimination method is used to find the values of variables in a system of equations.

Front

What is the first step in the elimination method?

Back

The first step is to align the equations and make the coefficients of one variable the same.

Front

How do you know which variable to eliminate first?

Back

Choose the variable that can be easily manipulated to have the same coefficient in both equations.
