Just multiply equation one by 2 and then substract it from equation two
You can easily get your answer...

I am not good at this math but i think it's either A or D

anonymous · Answer

Its D...
x+3y=-1       .......(1)
multipling by 2
2x+6y=-2      ........(2)
2x+2y=6      ..........(3)
(2)-(3)
4y=-8
y=-2
Substitute y=-2 in equation (1)
x-6=-1
x=5
so answer is D (5,-2)
