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
OpenStudy (anonymous):
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)
