#u = (-7)/12#

Explanation:

#9 - 6(4u - 1)=14+15#
First, we need to distribute the left side
#9 + (-6)(4u)+(-6)(-1)=14+15#
#9 - 24u + 6 = 14 + 15#
#-24u + 15 = 29#
Then, transfer 15 to the opposite side
#-24u = 29 - 15#
#-24u = 14#
Finally, divide both sides by #-24# to find #u#
#(-24u)/-24=14/-24#
#u=(-7)/12#
