**David Q/R**, Sunday, September 30, 2012 at 12:50pmYou won't be able to determine x and y uniquely from just a single equation: you would need two equations to do that. The best you can do with just one equation is to work out x in terms of y, or y in terms of x. The way you do that is to get all the x's on one side, and all the y's on the other. In this example, you'd do something like this:

5x - 3y - 4 = 4x - 2y - 12, so add 3y to both sides to get:

5x - 4 = 4x + y - 12. Now subtract 4x from both sides to get:

x - 4 = y - 12. So x = y - 8, or y = x + 8.
