An equation that is always true is an identity.
that is called the solution set
The variables of this equation are your letters: a, b, and c. Variables merely stand in an equation to represent values that we don't know. "Solving" an equation is the process by which we uncover those values. In this particular case, since there are three variables, we cannot discover their values unless we have two other equivalent equations (a system of equations).
A solution to an equation is a set of values for the variables in the equation which make it true.
The solution to an equation consists of the value (or values) of all the variables such that the equation is true when the variable(s) take those values.
An equation is a mathematical statement that may (or may not) be true, defined for some variables. Solving an equation is finding those values of the variables for which the equation or statement is true.
It is called the DOMAIN!

It is the set of values for all the variables in the equation which make the equation true.

A function of one variable is of the form y=f(x) where all you need to know in order to get values for y is the value of the independent variable, x. A function of two variables is of the form z=f(x,y) where you need to know the values of both x and y to get a value for z. A linear equation is simply and algebraic equation where all variables, regardless of how many there are, are raised to the power of one.
The equation which remains true for each set of variables in the table.
Constant variables are constant, they do not change. Derived variables are not constant. They are determined by the other values in the equation.
Literal equation refers to an equation in which the variables represent known values. This type of equation allows the representation of things like distance, interest, time, and slope as variables in an equation.
