  1. r - 2s = 14 Solve for s: Subtract r off both sides: -2s = 14 - r Multiply both sides by -1 to avoid trouble later: 2s = r - 14 Divide by 2: s = (r - 14)/2

  6. Since r^2 = (-r)^2, we can assume without loss of generality that r ≥ 0. For each fixed r ≥ 0, A(r) is a circle centered at (0, 0) with radius r. (When r = 0, then A(0) is simply {(0, 0)}.) Hence...
