Three Different Ways to Solve a System of Linear Equations?

A system of linear equations consists of multiple equations that use the same variable set, and which represent lines that exist on the same plane. A solution to a system of linear equations is the... Read More »

How to Solve Four-Variable Linear Equations?

Solving four-variable linear equations is often done with four different equations. Because of linearity, all variables are of first order, meaning all variables are raised to the power of one. The... Read More »

How to Solve a Three Variable Linear Equation?

Linear equations, equations that define the position of a line, typically involve only the x-axis and y-axis. Three-variable equations, however, include the z-axis, defining an equation that exists... Read More »

How to Solve a System of Two Linear Equations?

Linear equations are encountered in everyday life. For example, if 4 apples and 5 oranges cost $2, and 3 apples and 4 oranges cost $1.55, how much does each apple and each orange cost? This article... Read More »
