Solve for q.
9 + 3q = 4q

9 + 3q = 4qbring the like terms onto the same side, so since 3q and 4q are like terms, let us bring them to one sideso when we move positive 3q to the other side it will turn into negative 3q so...9 = 4q - 3qso when you subtract 3q from 4q you should get 1q which is basically qso it is ... 9 = qwhen we flip the equation it will be q = 9aand that will be your final answerq = 9

hope that helps :)
