They are recipes for finding the numeric value of a variable, assigned a "letter" name (hence "literal") that typically stands for some sort of real-world quantity, such as Volume, Temperature, Pressure, amount of interest an investment earned, and so on.

This variable has an established relationship to other quantities that are also assigned "letter" names in the recipe (the equation),that gives the relationship between (or among) the quantities. The deal is, if we know the values for all of the variables in the recipe except one, then we can plug those values into the recipe and solve for the one variable whose value we don't
