What is it called when there is an equation that is always true?
an identity? maybe a tautology? Comment by mgately: In the field of discrete mathematics (simplified the study of logic) any expression which always evaluates to true is in fact called a tautology. While less cool sounding, an expression which always evaluates to false is just called a contradiction.
What is the number that makes an equation true called?
It's callled the "solution" of the equation.
Is an identity that is true for every value called an equation?
No, it's the other way round - an equation that's true for every value of the variable(s) is called an identity. Of course, an identity is also an equation.
What is an equation that is true for every value of the variable?
legal equation * * * * * In mathematics, it is called an identity.
It is always helpful to rewrite an equation in standard form as a first step in solving it.?
True
What is an equation called that is not always true?
Seems to me like if it's not always true, then it's no equation.

Is an equation always equal or true?
No, it's not
What are the values of the variable that make an equation true called?
They are called the "solutions" of the equation.
If an equation is an identity what is true about the solution?
It is true for all permissible values of any variables in the equation. More simply put, it is always true.
What of an equation is any value that makes the equation true?
Such an equation is called an IDENTITY.
