What value of y makes this equation true when x equals 3?
In the equation x = 3, if x = 3, the equation is true, if x has any other value, it is not. The value of any other variable, such as y, is irrelevant. I would say that the answer is 0 because otherwise y is part of the equation which clearly it isnt.
An equation that is made true by any permissible replacement value for the variable is called?
It is an identity.
What is the value for a variable that makes an equation?
It's the value that when substituted in for the variable, makes the equation true. Ex: x + 1 = 3 The value 2, when substituted for the variable x, makes the equation true.
What is the value that makes an equation true?
solution
An equation that is true for every value?
identity
A value that makes an equation true?
Any number that makes an equation true is a 'solution of an equation'. it is a solution
Is to an equation is any value of the variable that makes the equation true?
Such a value is said to be a solution, or a root, of the equation.
What of an equation is any value that makes the equation true?
Such an equation is called an IDENTITY.
What is an equation that is not true for any value of a variable?
linear equation in one variable
Any value or values that make an equation or inequality true?
The solution.

How do you know if a value a is a solution to an equation?
If this value a satisfy the equation, then a is a solution for that equation. ( or we can say that for the value a the equation is true)
What does IDETITY means in math?
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.

What are identities trigonometry?
Identities are "equations" that are always true. For example, the equation sin(x) = cos(x) is true for x = pi/4 + kpi radians where k is any integer [ = 45 + 180k degrees], but for any other value of x the equation is not true. By contrast, the equation sin2(x) + cos2(x) = 1 is true whatever the value of x. This is an identity.
What is a linear equation that is not true for even one real number and therefor has no solution?
A linear equation in one variable. Case 1: A conditional equation: True only for a value of the variable. Ex. x + 2 = 3, True only when x is 1. Case 2: Identity Equation: Always true. Ex. x + 2 = x + 2, True for any value of x. Case 3: x + 1 = x + 5, False for any value of x. We call a solution any value of the variable that satisfies the equation, meaning if we replace the variable with that value, the equation becomes a true statement. Example: -2(x -3) = 8 - 2x -2x + 6 = 8 - 2x (add 2x and subtract 6 to both sides) 0 = 2 False. Since this equation, which is equivalent to the original equation, is false, then the original equation is also false. Meaning, there is no real number for x that could satisfy the equation. So there is no solution to the equation.
