<h3>9 + 3q = 4q</h3><h3>bring the like terms onto the same side, so since 3q and 4q are like terms, let us bring them to one side</h3><h3>so when we move positive 3q to the other side it will turn into negative 3q so...</h3><h3>9 = 4q - 3q</h3><h3>so when you subtract 3q from 4q you should get 1q which is basically q</h3><h3>so it is ... 9 = q</h3><h3>when we flip the equation it will be q = 9</h3><h3>aand that will be your final answer</h3><h3>q = 9</h3>
So-called simplifying, really means, "rationalizing the denominator", which is another way of saying, "getting rid of that pesky radical in the bottom"
