Solving simultaneous equations is one small algebra step further on from simple equations. Graphing a system of equations shows students the most visual representation. If the graphs are parallel lines, there is no point of intersection and no solution to the system. A consistent system is considered to be an independent system if it has a single solution, such as the example we just explored. The graph of a linear equation is a line. Solve a System of Linear Equations by Graphing. For a system of linear equations in two variables, we can determine both the type of system and the solution by graphing the system of equations on the same set of axes. Enter your equations in the boxes above, and press Calculate! Solving systems of equations with substitution. Each point on the line is a solution to the equation. We can verify the solution by substituting the values into each equation to see if the ordered pair satisfies both equations. Important InformationNot all boxes are used in the maze to avoid students from just figuring out the correct route. Another type of system of linear equations is an inconsistent system, which is one in which the equations represent two parallel lines. The ordered pair $\left(5,1\right)$ satisfies both equations, so it is the solution to the system. There are no points common to both lines; hence, there is no solution to the system.
