First can you change
2x + y = -12
To have y as the subject
Looks like y = ???
<span>5*s-(4*s)-(1/2) = -1/4-(4/8) // + -1/4-(4/8)
5*s-(4*s)-(1/2)-(-1/4)+4/8 = 0
5*s-4*s-1/2+1/4+4/8 = 0
s+1/4 = 0 // - 1/4
s = -1/4
s = -1/4
</span>
I hope I read it right, it's a bit blurry. The answer is C. 6/11. Hope it helps!
