.... simple, whole number equations. However, if the numbers are fractions, then the point of intersection might not fall directly on a point and therefore, it will not be accurate. Although it seems easy, this is not one of my preferred methods of solving systems of equations because it is not always easy to graph lines and to determine a point of intersection from a graph. One of the easiest ways to solve a system of equations is to solve by substitution. In order to use this method, it is preferable that either the x or the y in one of the lines has no coefficient. The method will work if there are coefficients before the variables, but it is easier ....
