Question

OPEN-ENDED Write an equation that is an identity.

Step-by-Step Solution

Answer

An example of an identity that is an equation is 3x + 6 = 3(x + 2).

Step 1. Definition.

Identity: If an equation is true for all values of x, then it is called an identity. An example of identity is: $2x+3=x+(x+3)$. 

Equation: An equation can be given by a combination of two expressions that are equated to each other. An example of an equation is $x+5=2x+9$.

Step 2. What to find?

We have to find an equation that is an identity.

Step 3. Calculation.

An example of an identity that is an equation is $3x+6=3(x+2)$.

Hence, $3x+6=3(x+2)$ is an identity which is an equation.
