Unlike equations (or inequalities), identities are always true. It is, therefore, not possible to solve them to obtain values of the variable(s).
not always.
Variable Equation. Equations typically always have (a) variable(s) so it's kind of like asking, "What a word that has letters called?" It's not quite the same, the question is valid. I'm just pointing out that it's a little redundant to say the following, but the best match for what you need would probably be: variable equation.
no
constant variable
No, tables are not ALWAYS the best way to find a value. They may be the easiest way or not.
You can replace a variable with an equal value or expression. Just make sure the same variable always gets the same value or expression.
They can be, but not always. Other methods (equations, graphs) may be the best way.

Equations always contain an
You undo one of the operations at a time, always with the aim of isolating the variable you want to solve for on one side.
x may not always represent a positive number because there are equations that make a variable a negative number

the y variable always changes and x is constant
