WebHere there are three solutions: In [2]:= Out [2]= To solve a system of equations, use a list in the first argument: In [3]:= Out [3]= Here there are two solutions to a simultaneous system of equations; each solution set is wrapped in its own list: In [4]:= Out [4]= Here the solution expresses one variable in terms of another: In [5]:= Out [5]= 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.
