Full solution

Q. Solve for rr.r+45r + 4 \leq 5
  1. Identify Operation: r+45r + 4 \leq 5\newlineWhich operation should we use to isolate rr?\newlineSince 44 is being added to rr in r+45r + 4 \leq 5, we should use subtraction to isolate rr.
  2. Isolate rr Using Subtraction: r+45r + 4 \leq 5\newlineSolve for rr.\newliner+4454r + 4 - 4 \leq 5 - 4\newliner1r \leq 1
