To determine the classification of the linear equation , apply the properties of equality. First, distribute the on the right side to get . Next, subtract from both sides to group the variable terms, which results in . The variables are completely eliminated, leaving a numerical statement that is universally true. Because the equation evaluates to a true statement regardless of the value of , the original equation is classified as an identity, meaning its solution set is all real numbers.
