See a solution process below:

Explanation:

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
