Q. Evaluate the expression for c=−2c = -2.\newline−15−3c=-15 - 3c = _____
  1. Identify expression and substitute: Identify the expression and substitute the value of cc. Substitute –2–2 for cc in the expression –15−3c–15 − 3c. Expression: –15−3(–2)–15 − 3(–2)
  2. Substitute value of cc: Multiply 33 by –2–2.\newline33 times –2–2 equals –6–6.\newlineBut since it's subtracting a negative, it becomes –15+6–15 + 6.
  3. Multiply and adjust sign: Evaluate –15+6–15 + 6.–15–15 plus 66 equals –9–9.
