Hey there!
The section that contains the solutions to the system of equations is B. Region B only.
This is because it is the area where the solutions for the two equations intersect and the solution would work for both of the equations.
Region A is not a solution to both systems because it does not include solutions to the second equation, and region C does not include solutions to the first equation, so any option containing A and C is incorrect, leaving only option B.
Hope this helps!
