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#
