Answer:

System A should be solved by elimination because you can easily cancel out the 3m to solve.

System B should be solved by substitution.  Since the an equation for the y value is given, you can easily substitute it into the other equation.

System C should be solved by graphing.  You don't have to worry about any slopes or intercepts to graph.  You can graph it using only whole numbers.
