Answer 1

This process of solving a formula for a given variable is called "solving literal equations". One of the dictionary definitions of "literal" is "related to or being comprised of letters", and variables are sometimes referred to as literals. So "solving literal equations" seems to be another way of saying "taking an equation with lots of letters, and solving for one letter in particular."

Answer 2

Well actually it depends on the question you're seeking...on a general note:
In the case of algebraic equations :
Define "like terms" by their variables and powers.
Factor by writing numbers as the product of two factors
Use the acronym PEMDAS to remember the order of operations.
