NettetSolving Systems of Equations in Two Variables by the Addition Method. A third method of solving systems of linear equations is the addition method, this method is also … NettetTo isolate y, first subtract 2x from both sides (4y = -2x + 100), then divide by 4 (y = -1/2 x + 25). This is the more common usage because this is a linear function in slope intercept form - y in terms of x or y dependent on x. To solve for x, subtract 4y from both sides (2x = - 4y + 100), then divide by 2 (x = - 2y + 50).
