What is the answer to 5p + 9c = p for c
5p + 9c = psubtract 9c from both sides=> 5p + 9c - 9c = p - 9csimplify=> 5p = p - 9csubtract p from both sides=> 5p - p = p - 9c - psimplify=> 4p = -9cdivide both sides by -9 (to isolate c) => 4p/ -9 = -9c/ -94p/-9 = c, or c = 4p/ -9
5p + 9c = p |subtract 5p from both sides9c = -4p |divide both sides by 9c = -4/9 p
