What is the answer to 5p + 9c = p for c

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
