How do I solve systems of linear equations?
All you need to do is enter each equation on a different line (press “Enter” to go to the next line) and finally click Solve all. After solving, you will even be shown a graphical representation of both equations, which will help you understand your answer better. You can even choose the method by which the system is solved, use the drop-down menu Solution | Settings, where “Substitution”, “Elimination” and “Cramer’s rule” are shown as options. You can also let Algebrator select which is the best method for your system, by picking “Smart Choice”. If you wish to solve the system graphically you could graph the equations (enter them the same way but press Graph All instead) and then identify the point where the lines intersect, if they do intersect.
