How could you check to see if the point (5, 6) is the solution to the Linear System of equations?

You would need to have the two equations in the system to check. Then, substitute the x-value of the point (5) into the first equation and the y-value (6) into the second equation. If both equations are true when you substitute, then (5, 6) is a solution to the system. If either equation is not true, then (5, 6) is not a solution.
