See a solution process below:

In this problem we are looking for the value of $y$ $y$ given the value of $x$ $x$ is $- 4$ $-4$ .

We can substitute $- 4$ $-4$ for $x$ $x$ in the equation and solve for $y$ $y$ :

$6 x - y = 7$ $6x - y = 7$ becomes:

$(6 \cdot - 4) - y = 7$ $(6 * -4) - y = 7$

$- 24 - y = 7$ $-24 - y = 7$

$24 - 24 - y = 24 + 7$ $color(red)(24) - 24 - y = color(red)(24) + 7$

$0 - y = 31$ $0 - y = 31$

$- y = 31$ $-y = 31$

$- 1 \times - y = - 1 \times 31$ $color(red)(-1) xx -y = color(red)(-1) xx 31$

$y = - 31$ $y = -31$
