Algebraic Expressions and Equations

Master algebraic expressions and equations! Learn to identify parts and solve problems.

Expression or Equation? Equationshave an EQUALsign (=).Expressions do NOT have an equal sign. Expression 2x + 5 2n 4 + 9 k Equation 2x + 5 = 7 2n = -10 10 + 3 = 4 + 9 40 = k Label the equation.
