This calculator only works with double sided equations such as 1x+5=2x-5 or 49c-9=200c-137 (variable can be any English letter) If your equation is something like x+5=40x-10 then put a one before the variable, in this case x, like, 1x+5=40x-10. Also if your equation looks like this, 3x=4x-1, then add "+0"s like 3x+0=4x-1
I made this calculator because I love math and also it might be a fun idea to make and/or do. This is 100% working so, yeah. Thanks for visiting!
