x-y=77
x: y=2 rest 25 rezulta ca x=2y +25
2y+25-y=77 rezulta ca y=77-25=52
x=77+52=129
x: y=2 rest 25 rezulta ca x=2y +25
2y+25-y=77 rezulta ca y=77-25=52
x=77+52=129
a-b=77
a:b= 2 rest 25
a= 2*b+25
2b+25-b=77
b=77-25
b=52
a= 52*2+25
a=104+25
a=129
a:b= 2 rest 25
a= 2*b+25
2b+25-b=77
b=77-25
b=52
a= 52*2+25
a=104+25
a=129
