( y - 1 ) : 105 = 125 x 80
( y - 1 ) : 105 = 10000
y - 1 = 10000 x 105
y - 1 = 1050000
y = 1050000 + 1
y = 1050001
(y-1):105=125x80
(y-1):105=10000
(y-1) =10000x105=1050000
y =1050000-1=1049999
Đơn giản thui !!!!!!!!!!!
(y - 1) : 105 = 10000
(y - 1) = 10000 x 105
y - 1 = 1050000
y = 1050001
Đáp số 1050001
(y-1):105=10000
y - 1=10000 x 105
y - 1= 1050000
y=1050001
\(\left(y-1\right):105=125.80\)
\(\left(y-1\right):105=10000\)
\(y-1=1050000\)
\(y=1050001\)
vậy \(y=1050001\)
(y-1) : 105 = 125 . 80
(y-1) : 105 = 1000
y - 1 = 1000 . 105
y - 1 = 1 050 000
y = 1 050 000 +1
y = 1 050 001
Vậy y = 1 050 001
y= 1500001
