#m = -100#

Explanation:

#1/4m + 9 = -16#

#m/4 + 9 = -16#

#m/4 + 9/1 = -16/1#

Multiply through by their LCM, LCM #= 4#

#4(m/4) + 4(9/1) = 4(-16/1)#

#cancel4(m/cancel4) + 4(9/1) = 4(-16/1)#

#m + 36 = -64#

Subtracting #36# from both sides;

#m + 36 - 36 = -64 - 36#

#m + 0 = -64 - 36#

#m = -100#
