all you need to do is plug in x = 1 and  y = 3
if it satisfies both the equations then it satisfies the system of equations

can you proceed now?

No, I need more help i'm kinda slow!

harsimran_hs4 · Answer

put x = 1 and y = 3 in the 1st equation of A option and tell if it satisfies or not?

anonymous · Answer

Ok, no it doesnt. Lol. I think it's C.

harsimran_hs4 · Answer

no answer is not c
so try again step by step
