A:
Answer:Step 2Step-by-step explanation:Process of elimination can help us here.Step one, write a system of equations. This is a given, so this can't be wrong.Step three, graph the equations. At first, this may seem wrong, but it works because of step four, Identify the x-value at the point of intersection. Neither of these can be wrong.That leaves us with step two.
