Q. Evaluate the expression for w=−1w = -1.\newline−13w−7=-13w - 7 = _____
  1. Write expression substitution: Write the expression −13w−7−13w − 7 after substituting w=−1w = −1.
    Substitute −1−1 for ww in −13w−7−13w − 7.
    −13(−1)−7−13(−1) − 7
  2. Substitute ww in expression: Evaluate –13(–1)−7–13(–1) − 7.\newline–13(–1)–13(–1) is the same as 1313 because the product of two negative numbers is positive.\newline13−713 − 7
  3. Evaluate expression: Subtract 77 from 1313. \newline13−713 - 7 equals 66.
