Answer:

\displaystyle [-8, -10]

Step-by-step explanation:

12 = x - 2[3x + 14]

12 = x - 6x - 28

12 = −5x - 28

+ 28 + 28

____________

\displaystyle \frac{40}{-5} = \frac{-5x}{-5}

\displaystyle -8 = x[Plug this back into both equations above to get the y-coordinate of −10]; \displaystyle -10 = y
