See a solution process below:

First, combine the like terms on the left side of the equation:

#2x - 1x + 9 = -6#

#(2 - 1)x + 9 = -6#

#1x + 9 = -6#

#x + 9 = -6#

Now, subtract #color(red)(9)# from each side of the equation to solve for #x# while keeping the equation balanced:

#x + 9 - color(red)(9) = -6 - color(red)(9)#

#x + 0 = -15#

#x = -15#
