#x=10#

#16-2.4x=-8#

Move #-8# to the left and #-2.4x# to the right.
#16+8=2.4x#
#24=2.4x#
#x=10#

#x=10#

#16-2.4x=-8#

#-2.4x=-8-16#

#-2.4x=-24#

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

#2.4x=24#

#x=cancel24^color(red)10/cancel2.4^color(red)1#

#x=10#

substitute #color(red)(x=10#

#16-2.4(color(red)10)=-8#

#16-24=-8#

#-8=-8#
