Alternate Math Solver can solve equations that contain a variable X towards this variable. The resulting equation will look like X=...You can solve new as well as save and open saved equations. A help file is available but there's no help for us and math, so here's an explanation from Alternate Tools.Example for an equation that contains variable X and numbers only:8 = (x*25)/(x+25)Solved towards X it will look like: x = 11.7647Equations may also include additional variables (f in the following case):exp(2*x) = 2*exp(x)+fWill become: x = log(1+sqr(1+f))While solving an equation the program will also provide the intermediate steps that lead to the solution.
