See a solution process below:

Step 1) Subtract #color(red)(9)# from each side of the equation to isolate the #u# term while keeping the equation balanced:

#u/8 + 9 - color(red)(9) = -1.24 - color(red)(9)#

#u/8 + 0 = -10.24#

#u/8 = -10.24#

Step 2) Multiply each side of the equation by #color(red)(8)# to solve for #u# while keeping the equation balanced:

#color(red)(8) xx u/8 = color(red)(8) xx -10.24#

#cancel(color(red)(8)) xx u/color(red)(cancel(color(black)(8))) = -81.92#

#u = -81.92#
