5p + 9c = p subtract 9c from both sides=> 5p + 9c - 9c = p - 9c simplify=> 5p = p - 9c subtract p from both sides=> 5p - p = p - 9c - p simplify=> 4p = -9c divide both sides by -9 (to isolate c) => 4p/ -9 = -9c/ -9 4p/-9 = c, or c = 4p/ -9

5p + 9c = p |subtract 5p from both sides

9c = -4p |divide both sides by 9

c = -4/9 p
