See the entire solution process below;

First, subtract #color(red)(3)# from each side of the equation to isolate the #w# term and keep the equation balanced:

#w/7 + 3 - color(red)(3) = -1 - color(red)(3)#

#w/7 + 0 = -4#

#w/7 = -4#

Now, multiply each side of the equation by #color(red)(7)# to solve for #w# while keeping the equation balanced:

#w/7 xx color(red)(7) = -4 xx color(red)(7)#

#w/color(red)(cancel(color(black)(7))) xx cancel(color(red)(7)) = -28#

#w = -28#
