Answer:Some equations may not have solutions and some may have one or more than one is because of the variables or how they are written
Step-by-step explanation:not 100% sure this is the correct answer,I tried my best.
A system of equations consists on a group of equations that we must solve at the same time.
From this, the solutions of a system of equations appear as the intersections between the graphs of the equations that conform the system.
So for example, if a system has two parallel lines (two lines that never intersect) that system will have no solution.
If a system has two different and not parallel lines, these lines will intersect at some point, so this system will have one solution.
And finally, if the system has twice the same line, the graphs of the lines will intersect in infinite points, thus, this system has infinite solutions.
