Multiply both sides of an equation by a nonzero constant. Add a nonzero multiple of one equation to another equation. WebSolving for a variable is also called isolating the variable, so you want to move everything away from it. To 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.
