890 : x = 35 dư 15
875 : x = 35
x = 875 : 35
x = 25
890 : x = 30 du 15
x = (890 - 15) : 35
x = 875 : 35
x = 25
890 : x = 35 (dư 15)
(890 - 15 ) : x = 35
875 : x = 35
x = 875 : 35
x = 25
890 : x = 35 dư 15
890 = 35.x+15
890 - 15 = 35.x
875 = 35.x
x=875:35
x=25
\(890\div x=35\) ( dư 15 )
\(x=890\div35\)
\(x=25\)
Vậy \(x=25\)
P/s : Học tốt !
\(890:x=35\left(dư15\right)\)
\(\Leftrightarrow x.35+15=890\)
\(\Leftrightarrow x.35=875\)
\(\Leftrightarrow x=875:35\)
\(\Leftrightarrow x=25\)
890:x=35 dư 15
x=(890-15):35
x=875:15
x= 25
890 : x = 35 dư 15
=> ( 890 - 15 ) : x =35
=> 875 : x = 35
=> x = 875 : 35
=> x = 25
Vậy x = 25
890 : x = 35 dư 15
<=> x = ( 890 - 15 ) : 35
<=> x = 875 : 35
<=> x = 25
Vậy x = 25
890 : x = 30 du 15
x = (890 - 15) : 35
x = 875 : 35
x = 25
hok tốt
890 : x = 35 dư 15
x = ( 890 - 15 ) : 35
x = 875 : 35
x = 25
Vậy x = 25
