Q. Evaluate the expression for x=−6x = -6.\newline−8−2x=-8 - 2x = _____
  1. Substitute xx with −6-6: Substitute xx with −6-6 in the expression –8−2x–8 − 2x.\newlineSubstitute −6-6 for xx in –8−2x–8 − 2x to get –8−2(−6)–8 − 2(-6).
  2. Evaluate expression: Evaluate –8−2(−6)–8 − 2(-6).–8−2(−6)=–8+12–8 − 2(-6) = –8 + 12 (since multiplying a negative by a negative gives a positive).
  3. Add numbers: Add −8-8 and 1212.\newline−8+12=4-8 + 12 = 4.
