https://info.5y1.org/equations-with-variables_1_0a361c.html
Solving Systems of Equations by Substitution **BASIC IDEA- You are taking 2 equations with 2 different variables and writing it as 1 equation with 1 variable. Example 1. Use substitution to solve the following system of equations. X + 4y = 1. 2x – 3y = -9. Step1 –Choose a variable to solve for in either equation.

Solving Systems of Linear Equations in Three Variables
A system of equations in three variables is any system that essentially contains three unknown quantities. The variables x, y, and z are usually used to represent these unknown values. Needless to say, a system of linear equations in three variables is a system that meets both conditions listed above. While a system of equations can contain any ...

The given problem is expressed as a system of linear equations and then solved to determine the value of the variables. Sometimes, the system will consist of three equations but not every equation will have three variables. Example three is one such problem. Example 1: Solve the following problem using your knowledge of systems of linear equations.
