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

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.

When you find the value of a variable you solve or check an equation?

when you find the value, you SOLVED the equation. you CHECK the equation when you substitute the value in the variables place and check that the equation is true.
