Systems of Linear Equations. A Linear Equation is an equation for a line. A linear equation is not always in the form y = 3.5 − 0.5x, It can also be like y = 0.5 (7 − x) Or like y + 0.5x = 3.5. Or like y + 0.5x − 3.5 = 0 and more.
Apr 24, 2017 · A system of linear equations involves two relationships with two variables in each relationship. By solving a system, you are finding where the two relationships are true at the same time, in other words, the point where the two lines cross. Methods for solving systems include substitution, elimination, and graphing.
Systems of equations with graphing. Walk through examples of solving systems of equations by finding the point of intersection. We can find the solution to a system of equations by graphing the equations. Let's do this with the following systems of equations: First, let's graph the first equation y = 1 2 x + 3 .

A "system" of equations is a set or collection of equations that you deal with all together at once. Linear equations (ones that graph as straight lines) are simpler than non-linear equations, and the simplest linear system is one with two equations and two variables.
You will find systems of equations in every application of mathematics. They are a useful tool for discovering and describing how behaviors or processes are interrelated. It is rare to find, for example, a pattern of traffic flow that that is only affected by weather.

When solving systems of linear equations, one method is to graph both equations on the same coordinate plane. The intersection of the two lines represents a solution that satisfies both equations. Other, more mathematical, methods may also be used.
