Which system of linear equations has the ordered pair (-2,8) as its solution?

y - 2x = 12 and x - 2y = -18
x – 2y = 12 and y - 2x = -18
y + 2x = 12 and x + 2y = -18
x + 2y = 12 and y + 2x = -18

Answer:

y - 2x = 12 and x - 2y = -18

$for \: y - 2x \\ 8 - 2( - 2) \\ 8 + 4 \\ = 12 \\ for \: x - 2y \\ - 2 - 2(8) \\ = - 2 - 16 \\ = - 18$
