A:
Answer:[tex]\displaystyle [-7, -7][/tex]Step-by-step explanation:{2x - 6y = 28{−x - y = 14−⅙[2x - 6y = 28]{−⅓x + y = −4⅔{−x - y = 14____________[tex]\displaystyle \frac{-1\frac{1}{3}x}{-1\frac{1}{3}} = \frac{9\frac{1}{3}}{-1\frac{1}{3}} \\ \\[/tex][tex]x = -7[/tex][Plug this back into both equations above to get the y-coordinate of −7]; [tex]\displaystyle -7 = y[/tex]I am joyous to assist you anytime.
