Answer:

See a solution process below:

Explanation:

First, subtract #color(red)(15)# from each side of the equation to isolate the #x# term while keeping the equation balanced:

#-color(red)(15) + 15 - x/8 = -color(red)(15) + 4#

#0 - x/8 = -11#

#-x/8 = -11#

Now, multiply each side of the equation by #color(red)(-8)# to solve for #x# while keeping the equation balanced:

#color(red)(-8) xx x/-8 = color(red)(-8) xx -11#

#cancel(color(red)(-8)) xx x/color(red)(cancel(color(black)(-8))) = 88#

#x = 88#
