Multiply each side of the equation by #color(red)(96)# to solve for #x# while keeping the equation balanced:
#color(red)(96) xx 32.4/108 = color(red)(96) xx x/96#
#color(red)(96) xx 32.4/108 = cancel(color(red)(96)) xx x/color(red)(cancel(color(black)(96)))#
#(96 xx 32.4)/108 = x#
#x = (96 xx 32.4)/108#
We can now factor the fraction to simplify it:
#x = (12 xx 8 xx 32.4)/(12 xx 9)#
#x = (color(red)(cancel(color(black)(12))) xx 8 xx 32.4)/(color(red)(cancel(color(black)(12))) xx 9)#
#x = (8 xx 32.4)/9#
#x = (8 xx 9 xx 3.6)/9#
#x = (8 xx color(red)(cancel(color(black)(9))) xx 3.6)/color(red)(cancel(color(black)(9)))#
#x = 28.8#
