Question 709958

A system of equations is a collection of two or more equations with a same set of unknowns. 
In solving a system of equations, we try to find values for each of the unknowns that will satisfy every equation in the system.

The equations in the system can be linear or non-linear. 


Example of an algebraic statement of the same system of the equations:

{{{3x-2y=1}}}.....eq.1
{{{x+y=3}}}.....eq.2

A system of linear equations can be solved four different ways:


        {{{Substitution}}}

        {{{Gaussian}}}{{{ Elimination}}}

        {{{Matrices}}}

        {{{Graphing}}}

let's use   {{{Graphing}}} to solve the system above:
