Q. Evaluate p+(−q)−2 p+(-q)-2 where p=−3 p=-3 and q=5 q=5 .
  1. Given Values: We are given:\newlinep=−3p = -3\newlineq=5q = 5\newlineExpression = p+(−q)−2p + (-q) - 2\newlineIdentify the expression after substituting the values of pp and qq.\newlineSubstitute −3-3 for pp and 55 for qq in the expression p+(−q)−2p + (-q) - 2.\newlineq=5q = 500
  2. Substitute Values: Simplify the expression by adding the numbers. \newline−3+(−5)-3 + (-5) gives us −8-8.\newlineNow, we have −8−2-8 - 2.
  3. Simplify Expression: Subtract 22 from −8-8. −8−2-8 - 2 equals −10-10.
