See a solution process below:

Explanation:

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

#-color(red)(1) + 9 = -color(red)(1) + 1 + m/7#

#8 = 0 + m/7#

#8 = m/7#

Step 2) Multiply each side of the equation by #color(red)(7)# to solve for #m# while keeping the equation balanced:

#color(red)(7) xx 8 = color(red)(7) xx m/7#

#56 = cancel(color(red)(7)) xx m/color(red)(cancel(color(black)(7)))#

#56 = m#

#m = 56#

56

Explanation:

#9=1+m/7#

#9-1=m/7#

#8=m/7#

#8*7=m#

#m=56#
