solve -9p - 5m = 60 how do you solve this step by step please. not just the answer I need to learn how you do this problem. solv
Scrat [10]
         -9p - 5m = 60
-9p - 5m + 5m = 5m + 60
                 -9p = 5m + 60
                  -9          -9
                    p = ⁻⁵/₉m - 6²/₃

You have to add 5m on each side in order to find the value of p. then, you have to divide it by -9 in order to find the value of p.
