Full solution

Q. Question 2525\newlineEvaluate the expression when a=−6 a=-6 and y=6 y=6 .\newlinea−8y a-8 y
  1. Substitute values into expression: Substitute the given values into the expression. a−8y=(−6)−8(6)a - 8y = (-6) - 8(6)
  2. Perform multiplication: Perform the multiplication.\newline(−6)−8(6)=(−6)−48(-6) - 8(6) = (-6) - 48
  3. Subtract to find result: Now, subtract 4848 from −6-6.(−6)−48=−54(-6) - 48 = -54
