SIMPLIFYING EXPRESSIONS VS. SOLVING EQUATIONS

Examples: “Simplify 2x + 3x” or “Simplify 7 • 6 – 8”. We may also be asked to "Evaluate 5x - 2y for x = 3 and y = 4." This latter means to substitute 3 in place of x and 4 in place of y and then simplify the expression to get a single number answer. Equations: Equations are algebraic “sentences.” They consist of two algebraic ... ................
