#x = 2#

#3/2x -15 color(red)(+15) = -12 color(red)(+15)#

#color(blue)(2 xx) 3/2x = color(blue)(2 xx)3#

#cancel2 3/cancel2x = color(blue)(2 xx)3#

#3x = 6#

#x = 2#

Or we can multiply the whole equation b 2 to get rid of the denominator.

#color(blue)(2 xx)3/2x -color(blue)(2 xx)15 = color(blue)(2 xx)(-12) #

#3x - 30 = -24#

#3x = -24+30#
#3x = 6#
#x = 2#
