#m = -14#

As per the question, we have

#m/-7 + 9 = 11#

#:. -m/7 +9 = 11#

#:. (-m + 63)/7 = 11#

#:. -m +63 = 77#

#:. -m = 14#

#:. m = -14 #

Hence #m = -14# is the solution to this equation.

#m=-14#

#m/-7+9=11#

multiply both sides by#-7#

#:.m-63=-77#

#:.m=-77+63#

#:.m=-14#

~~~~~~~~~~
check:-

substitute #m=-14#

#:.-14/-7+9=11#

#:.2+9=11#

#:.11=11#
