Universal Simplifier and Solver

 Welcome to Graphical Universal Mathematical Expression Simplifier and Algebra Solver (GUMESS). It solves most middle school algebra equations and simplifies expressions, and it SHOWS ALL WORK. It is free to use.Enter expression to be simplified, or equation to be solved. I will figure out if what you typed is an equation. Enter Expression ==>     Examples: `x^2-2x=-1, 3x-x-x+a-a=5, (x^2-1)/(x+1), 2x-(x+x)` Single letter variables only, no functions, xy means x*y, x(x-1) means x*(x-1), sin(x) means s*i*n*(x)

You must use the "*" (star) symbol for all multiplications! x(x+1) is WRONG! It means a function x of x-1. x*(x-1) is right. Use the ^ (caret) for exponentiation. x^2 means x squared. x/2y means
