See the entire solution process below:

To find the $y$ $y$ value for the ordered pair substitute $3$ $color(red)(3)$ for $x$ $color(red)(x)$ in the equation and solve for $y$ $y$ :

$6 x - y = 7$ $6color(red)(x) - y = 7$ becomes:

$(6 \times 3) - y = 7$ $(6 xx color(red)(3)) - y = 7$

$18 - y = 7$ $18 - y = 7$

$- 18 + 18 - y = 7 - 18$ $color(red)(-18) + 18 - y = 7 color(red)(- 18)$

$0 - y = - 11$ $0 - y = -11$

$- y = - 11$ $-y = -11$

$- 1 \times - y = - 1 \times - 11$ $color(red)(-1) xx -y = color(red)(-1) xx -11$

$y = 11$ $y = 11$

The ordered pair is $(3, 11)$ $(3, 11)$
