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.
legal equation * * * * * In mathematics, it is called an identity.
A function is an equation (a relation) which has only one y-value for every x-value. If a single x-value has more than one y-value, the equation is no longer called a function.
An identity is an equation that is always true, for any value of the variable or variables. Here are some examples: x + x = 2x a + b = b + a x1 = x
how about X = X
Strictly speaking the above equation is a tautological equation or an IDENTITY. An identity is true for all values of any variables that appear in it. Thus, the above "equation" is true for all value of x. - that is, it has infinitely many solutions.

An identity.
Such an equation is called an IDENTITY.
It is an identity.

No. It is only true for one value of x so it is an equation. An identity must be true for all values of x. An identity equation is like saying "in other words ... ".

An identity is an equation that is always true, for any value of the variable or variables. Here are some examples: x + x = 2x a + b = b + a x1 = x

An identity is an equation that is always true.For example, 2x + 5 = 11 is only true if x = 3. This is a regular equation, not an identity.On the other hand, 2x + x = 3x is true, for any value of x. Therefore, it is an identity.
An identity is an equation that is always true, no matter what value you replace for the variable.To give a simple example, 2x + 3x = 5x is true for any x.An identity is an equation that is always true, no matter what value you replace for the variable.To give a simple example, 2x + 3x = 5x is true for any x.An identity is an equation that is always true, no matter what value you replace for the variable.To give a simple example, 2x + 3x = 5x is true for any x.An identity is an equation that is always true, no matter what value you replace for the variable.To give a simple example, 2x + 3x = 5x is true for any x.
