Step-by-step explanation:

1) She solved the first equation for x:

$2x - y = 6\\\\2x= 6+y\\\\x = (6+y)/2$

2) Plug x into the second equation:

$y = -3x + 4\\y = -3((6+y)/2) + 4\\\\y - 4 = (-18 -3y)/2\\2y - 8 = -18 - 3y\\5y -8 = -18\\5y = - 10\\y = -2$

3) Plug y into the first equation to find x:

$2x - y = 6\\\\2x - (-2) = 6\\\\2x+2=6\\\\2x = 4\\x=2$

Complete the interval: (2, -2)
