Q. What value of ww is a solution to this equation?\newlinew+11=20w + 11 = 20\newlineChoices:\newline(A)w=8w = 8\newline(B)w=9w = 9
  1. Isolate w: Step 11: Isolate w in the equation.\newlineGiven equation: w+11=20w + 11 = 20.\newlineSubtract 1111 from both sides to isolate w:\newlinew+11−11=20−11w + 11 - 11 = 20 - 11,\newlinew=9w = 9.
  2. Check solution: Step 22: Check the solution by substituting back into the original equation.\newlineSubstitute w=9w = 9 back into the original equation:\newline9+11=209 + 11 = 20,\newline20=2020 = 20.
