B

Step-by-step explanation:

elimination

4x - y = 8

6x + y = 2

+

10x = 10

x = 1

since x = 1, we can subtitute x to one of those equations

4x - y = 8

4(1) - y = 8

4 - 8 = y

y = 4 - 8

y = -4

x,y = 1,-4

B is correct

Step-by-step explanation:

you add the two equations together. So 4x + 6x  equals what? 10x. we know that y and -y cancel each other out. and then we all know that 8+2 is 10. now we have 10x=10 so x=1. We replace x for one and then we have 4 - y =8 so y has to equal -4 and there you have your answer, b

10
