To match the solutions with their system, we'll substitute the first point into the first system. If the point is a solution to both equations, it's a solution ot the system.
The equality is true for the second equation but not for the first one. A solution to a system of equations has to satisfy all
cannot be a solution to the first system. Let's try the second point,
Both equations are satisfied for
Thus, it's a solution to the system. Continue with B and check with the first point.
It's a solution! This means that the last point must be a solution to the last system of equations. Let's find out.
We have now paired the three solutions with the three systems.
