Substitution Method for Verification

The substitution method involves replacing the variable in an equation with a candidate value to test whether the resulting expression is true. When checking if a candidate solution satisfies a linear equation, the value is substituted in place of the variable, and the expression is simplified. If the equality holds, the candidate is a valid solution; otherwise, it is not.

Linear Equations

A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and a single variable. Linear equations are characterized by their highest power of the variable being one and typically take the form ax + b = c, where a, b, and c are constants. They are fundamental in algebra and are used to model relationships with a constant rate of change.
