Hello to all I will take a simple example. How can you easily transform using Mathematica the following functional expression y = 3/2 x + 1 into its general equivalent: 3 x - 2 y + 2 = 0 This general form exists because y == 3/2 x + 1 // FullSimplify returns True. Is the answer given valid whatever the complexity of the initial equality expression known to be true (with up to three unknown variables). Thanks Sigismond Kmiecik
