One way of solving a linear system is by graphing. The solution to the system will then be in the point in which the two equations intersect. Solve the following system of linear equations leftbeginmatrix y2x4 y3x2 end.

The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently. In this example the ordered pair latex4 7latex is the solution to the system of linear equations. We can verify the solution by substituting the values into each equation to see if the ordered pair satisfies both equations.

To solve a system of linear equations by graphing. Graph the first equation. Graph the second equation on the same rectangular coordinate system.

Determine whether the lines intersect are parallel or are the same line. Identify the solution to the system. There are an infinite number of solutions.

If you have a system of linear equations the solution for the system is the value that makes all of the equations true. For two variables and two equations this is the point where the two graphs intersect. The coordinates of this point will be the solution for the two variables in the two equations.

Solve systems of two linear equations in two variables algebraically and estimate solutions by graphing the equations. Solve simple cases by inspection. For example 3x 2y 5 and 3x 2y 6 have no solution because 3x 2y cannot simultaneously be 5 and 6.
