What is the Elimination Method in solving systems of equations?

Back

The Elimination Method is a technique used to solve systems of linear equations by eliminating one variable, allowing for the solution of the remaining variable.

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

Back

To eliminate a variable, you can multiply one or both equations by a number so that the coefficients of one variable are opposites, allowing you to add or subtract the equations.

Given the equations 2x + 3y = 6 and 4x + 6y = 12, what can you conclude?

Back

The second equation is a multiple of the first, indicating that the two equations represent the same line and have infinitely many solutions.

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

Back

A system has no solution if the lines represented by the equations are parallel and never intersect.

What does it mean if a system of equations has exactly one solution?

Back

A system has exactly one solution if the lines represented by the equations intersect at a single point.

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

Back

A system has infinitely many solutions if the equations represent the same line, meaning every point on the line is a solution.
