<span>Selections (a, b, d) are the most correct answers. To begin, 2x is equal to -8 when x is (-4). Adding 0 to this (for y) gives -8, which is the answer for the first equation. Doing the same for the second equation gives (-4 - 0) = -4, which shows that the second equation is also correct. Since both equations are satisfied by this ordered pair, it shows that the pair (-4,0) is a solution to the entire system.</span>
