Solving Systems of Equations by Elimination

These flashcards cover the key concepts and steps involved in solving systems of equations using the elimination method.

Elimination Method

A mathematical procedure used to eliminate one variable in a system of equations to solve for the others.

Step 1

Make sure the equations are lined up!

Step 2

Add or subtract the equations to eliminate the variable with common coefficients.

Step 3

Solve for the remaining variable.

Step 4

Substitute your answer into either original equation and solve for the other variable.

System of Equations

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

Common Coefficients

The coefficients that are the same in front of the variables in the equations.

Substitution Method

A technique used to solve a system of equations where one variable is isolated and substituted into another equation.
