Answer:
Check below
Step-by-step explanation:
First, we need to know what a system is.
What is a system of equations?
A system of equations is two or more equations that have common solutions. Thus, if the system remains true, if [tex]x=1[/tex] to one equation and we know there are solutions to the system, the [tex]x[/tex] in the other equations of the system must also equal to 1.
Because the [tex]x[/tex] - and [tex]y[/tex] - values will be the same in a system, this means when graphing, the graphs of the equations of the system will at some point intersect, indicating that the intersecting point is a solution.
Thus, when we solve a system by graphing, we look at the intersecting points.
If there are none, then there are no solutions to the system.
