Add 2y to both sides. = Next subtract 4 from each side. = Now divide each side by 2 to isolate the y variable. = Now repeat the process for the second equation. Subtract x from both sides = Now divide both sides by 2 to isolate the y variable = Now that both equations are in Slope-intercept form, graph the y intercept of each and use the slope to graph a second point. Compare the graphs of the two equations. Note that they intersect at one point only. This means that the 2 equations have one unique solution and are classified as independent.
