A literal equation is an equation where variables represent known values.
Variables may represent things like distance, time, velocity, interest, slope, etc.
The slope formula is a literal equation.
Y = MX + B
The distance that an object falls, in t seconds, is a literal equation.
So you’re working on a problem, and you identified the correct formula.
What do we when the variable that you need is not by itself?
In the above equation, how do we get t by itself?
By isolating the variable. In this tutorial, you’ll learn how to do this.
