Definition
An identity equation is true for all values of the variable(s).
Description
Identity equations are equations that hold true for all values of the variable(s). For example, the equation
2(x + 1) = 2x + 2
is an identity because it is true for any value of x. These equations are used to express mathematical identities and properties. In the equation above, the identity results from the use of the distributive property.
In real-world applications, identity equations help in simplifying expressions and proving mathematical theorems. Understanding identity equations is essential for students to recognize universal truths in mathematics and apply them in various contexts.
