No solution

First push all the variables to one side. We get,

#9x-8x-x# = #-12-1#

we get,

#0# = #-13#

This however is not possible. This means that the equation has no solution

There are no solutions

#12-x=8x-1-9x#

#12-x = -x - 1#

Add #x# on both sides

#12 - x + x = -x - 1 + x#

#12 = -1#

Then subtract #12# from both sides

#12 - 12 = -1 -12#

#0=13#

Thus,

There are no solution!
