The correct understanding of the solution to a system of equations is:
The coordinates of the ordered pair(s) that satisfy both equations in the system. In other words, the values of x and y that will make the equations true. Also, when a system of equations is graphed, the solution will be all points of intersection of the graphed lines.
This means that if you have a system of equations, the solution represents the point(s) (x, y) where the equations intersect when graphed, indicating values that make both equations true simultaneously. If the lines do intersect, there is a unique solution (one intersection point). If the lines are parallel, there is no solution, and if the lines coincide, there are infinitely many solutions.
