Please help me ASAP!!
Sati [7]

The answer is D, i.e. the system was solved via elimination


If you multiply the first equation by 5, the system becomes


\left \{ {{-5x-10y=35} \atop {5x-6y=-3}} \right.


If you sum the two equations, you get


-16y = 32


And so if you substitute the second equation of system A with this new equation, you'll get system B.
