#color(brown)(x=4#

#9-2x=6x-23#

#:.-2x-6x=-23-9#

#-8x=-32#

multiply L.H.S and R.H.S. by #color(brown)(-1#

#:.8x=32#

#:.x=32/8#

#:.color(brown)(x=4#

substitute #color(brown)(x=4#

#:.9-2(color(brown)4)=6(color(brown)4)-23#

#:.9-8=24-23#

#:.1=1#

#x=4#

Given -

#9-2x=6x-23#

Take all the constant terms to right hand side and unknowns to the left hand side.

#-2x-6x=-23-9#
#-8x=-32#
#x=(-32)/(-8)=4#
#x=4#
