So A literal Equation is practically made up of all letters ( also known as variables) So to answer one you have to try an isolate the variable for example * ax + b = c * You want to isolate * x *. You aren't trying to solve for x like you would for any other equation. You then have to do inverse operations. Below I have added a screenshot picture because I have done an example for you so that you can better understand what I'm explaining. I hope this helps you! :)
