It is called a constant and it value remains the same.
To be equivalent.

Like Fractions
EQUIVALENT EQUIVALENT IS TO HAVE THE SAME VALUE.
It means having the same value is to be equivalent as for example 1/2 has the same value as 2/4 because they are both equivalent fractions.
Same
An equation, or, perhaps an equality. 5X - 5 = 20 this equation has the same value that will satisfy it, with some manipulation this is two expressions having the same value 10 - 6 = 2 + 2
It is called a constant and it value remains the same.
They are called: Identical equations or IdentitiesSee: http://www.tutorvista.com/search/value-algebraic-expressions-33 - -7 = ss = -26
