In the paragraphs below I will introduce to you three different systems of equations and how to solve them. One way to solve an equation is to graph. There are three different steps in graphing equations to solve. The first thing you want to do is put the given equation into slope-intercept form ( y = mx + b ). For example : if you are given the equation x + y = 6 , to put that into slope-intercept form you must subtract the x from both sides. Therefore, you would end up with y = -x ...
