Q. Evaluate the expression for p=−3p = -3.\newline3p−7=3p - 7 = _____
  1. Substitute p=−3p = -3: Substitute p=−3p = -3 into the expression 3p−73p − 7.\newlineSubstitute −3-3 for pp in 3p−73p − 7 to get 3(−3)−73(-3) − 7.
  2. Evaluate 3(−3)3(-3): Evaluate 3(−3)−73(-3) - 7.\newline3(−3)3(-3) gives us −9-9, so we have −9−7-9 - 7.
  3. Add −9-9 and −7-7: Add −9-9 and −7-7 together.−9−7-9 - 7 equals −16-16.
