X-suma initiala

1/4 din x= 1/4 * x= 1/4 * x=  x/4 -prima data

x-x/4= (4x-x)/4= 3x/4 -restul

1/6 din 3x/4= 1/6 * 3x/4= x/8 -a doua oara

3x/4-x/8= (6x-x)/8= 5x/8 -noul rest 

1/3 din 5x/8+120 = 1/3 * 5x/8 +120 = 5x/24 +120= (5x+2880)/24-a treia oara 

5x/8 -(5x+2880)/24= (15x-5x-2880)/24= (10x-2880)/24 -noul nou rest

(10x-2880)/24=  600

10x-2880=14400

10x=14400+2880

10x=17280

x=1728
