Such a system is called an overdetermined system.
Then replace another equation with these variable to bring all the terms with same variable and constant.

This method is appropriate for the simplest kinds of linear systems and we will use this method to solve the system above.
The number of equations in a system, as well as the number of variables, is not limited.If the lines are parallel, then there are no point of intersection and we have no solution.Practice: Solving Systems of Equations (3 Different.The only thing you have to do is to draw the lines based on the given equations and then visually determine the point in which the lines cross paths.If the lines lie one over the another, then there are infinitely many solutions.
