What is it called when an equation is always true?
In math, an equation that is always true is called an identity.
It is always helpful to rewrite an equation in standard form as a first step in solving it.?
True
A value that makes an equation true?
Any number that makes an equation true is a 'solution of an equation'. it is a solution
What equation is true for some values of its variable and is not true for others?
No equation can have that property. It cannot be an equation if it is not true. If necessary, the domain must be amended. An equation can have different forms over different parts of its domain.
Give an example of an equation that is an identity?
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
What is it called when an equation is always true?
In math, an equation that is always true is called an identity.
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.
What a word of An equation that is always true?
Identity equation
What is an equation that is true regardless of the values of the variables called?
An equation that is always true is an identity.
Is an equation always equal or true?
No, it's not
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.
Is the solution to an equation any number that makes the equation true?
not always but most of the time yes
What is the word for a number that makes an equation true?
Solution. A solution of an equation is a number that satisfy the equation. This means that if you replace this number on the equation and check it, the equation will be true. When you solve an equation you can find some roots, but not all of them satisfy the equation. Thus always check your answers after resolving your equation, and eliminate as solution the answers that don't make the equation true or undefined.

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.
An equation always have two sides namely LHS and RHS it is true?
Yes
It is always helpful to rewrite an equation in standard form as a first step in solving it.?
True
