Use the substitution method to solve the system of equations. y = –4x 8x – y = 6 a.(2, –8)b. (1, –4) c.1/2-4 d.1/2-2

y= -4x and 8x-y=6

what you do is switch the negative y to the other side and move the positive 6 to the other side thus making y=8x-6.

I don't get what those numbers are on the question but the way you solve it is by combining them and putting one y into the other

8x-6=-4x   12x=6   6/12=x   .5=x

then you plug in x to find y in whichever equation:

-4x=y   -4(.5)=y   -2=y

so the final answer would be (.5,-2)

D. (1/2,-2)
