Question

Solve the system of equations 2r - 6y= 28 -x-y = 14 PLEASE HELP

Answer 1

Answer:

$\displaystyle [-7, -7]$

Step-by-step explanation:

{2x - 6y = 28

{−x - y = 14

−⅙[2x - 6y = 28]

{−⅓x + y = −4⅔

{−x - y = 14

____________

$\displaystyle \frac{-1\frac{1}{3}x}{-1\frac{1}{3}} = \frac{9\frac{1}{3}}{-1\frac{1}{3}}$

$x = -7$[Plug this back into both equations above to get the y-coordinate of −7]; $\displaystyle -7 = y$
