Answer:
[tex]\displaystyle [-8, -10][/tex]
Step-by-step explanation:
12 = x - 2[3x + 14]
12 = x - 6x - 28
12 = −5x - 28
+ 28 + 28
____________
[tex]\displaystyle \frac{40}{-5} = \frac{-5x}{-5}[/tex]
[tex]\displaystyle -8 = x[/tex][Plug this back into both equations above to get the y-coordinate of −10]; [tex]\displaystyle -10 = y[/tex]
