See a solution process below:

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

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

$6x - y = 7$ becomes:

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

$-24 - y = 7$

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

$0 - y = 31$

$-y = 31$

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

$y = -31$
