Solver - Solving Linear Equations

By: omer nawaz on Saturday, 27 December 2014 | 05:01

Linear equations are the most algebraic expressions used in different fields of science, from engineering through the science of human behavior to reach medical areas . 

A linear equation receives this name because when we get on a plane to graph results in the graph of a straight line. 

We linear equations with two or more variables the representation of these equations can be: 
  • Two variables -      3x + 2y = 8 
  • Three variables -   3x - 5y + 6z = -10 
  • Four variables -     w - 9x + 5y - 8z = -15

To solve a system of linear equations, we need to have the same number of equations and variables, that is, if I have a system of two variables , I need two equations to solve , if I have three variables , I need three equations and so on.
