  0.5x+2)/0.03-x=0.3(0.5x+2)/0.2-(10+11/12)

  100*(0.5x+2)/100*0.03-x=10*0.3(0.5x+2)/10*0.2-(10+11/12)

  100*(0.5x+2)/3-x=3(0.5x+2)/2-(10+11/12)

  (50x+200)/3-x=3*1/2(x+4)/2-(10+11/12)

  (50x+200)/3-x=3(x+4)/4-(10+11/12)

  12*(50x+200)/3-12*x=12*3(x+4)/4-12*(10+11/12)

  4*(50x+200)-12x=9(x+4)-120-11

  200x+800-12x=9x+36-131

  188x+800=9x-95

  188x-9x=-95-800

  179x=-895x=-5
