## What is equation method?

The equation method utilizes the profit equation introduced earlier.

Profit=Selling price−Variable Expenses−Fixed Expenses.

Also, let’s revisit the contribution margin concept and some shortcuts.

Contribution margin=Selling price−Variable expenses.

## What are the different ways to solve systems of equations?

The three methods most commonly used to solve systems of equation are substitution, elimination and augmented matrices. Substitution and elimination are simple methods that can effectively solve most systems of two equations in a few straightforward steps.

## What are the 3 systems of equations?

In order to solve systems of equations in three variables, known as three-by-three systems, the primary goal is to eliminate one variable at a time to achieve back-substitution. A solution to a system of three equations in three variables (x,y,z), ( x , y , z ) , is called an ordered triple.

## What are two algebraic methods used to solve systems of equations?

The algebraic method refers to various methods of solving a pair of linear equations, including graphing, substitution and elimination.

## What are the four methods of solving quadratic equations?

The four methods of solving a quadratic equation are factoring, using the square roots, completing the square and the quadratic formula.
