Question

In #9 you need to multiply ONLY ONE equation in order to have matching coefficients, and then use Addition or Subtraction to solve for "x" and "y". You don't need to graph.

In #11 you need to multiply BOTH equations in order to have matching coefficients, and then use the adding or subtracting method to solve for "x" and "y". You don't need to to graph.
