Full solution

Q. Solve for ww.\newline1w9<8-1w - 9 < -8
  1. Add 99 to isolate term: Add 99 to both sides to isolate the term with ww.1w9+9<8+9-1w - 9 + 9 < -8 + 91w<1-1w < 1
  2. Divide by 1-1 and flip: Divide both sides by 1-1, remembering to flip the inequality sign because dividing by a negative number reverses the inequality.\newline1w/1>1/1-1w / -1 > 1 / -1\newlinew>1w > -1
