890:x =35 dư 15
890:x=35 dư 15
890:x=35 dư 15
nên \(35x=890-15=875\)
hay x=25

\(890:x=35dư15\)
\(x=890:35+15\)
x= ??? ko chia hết!
1. 890 : x =35 dư 15
Lời giải:
$890=x\times 35+15$
$890-15=x\times 35$
$875=x\times 35$
$x=875:35=25$
890:x=35 dư 15
\(890:x=35\left(dư15\right)\)
\(\Rightarrow x=\frac{\left(890-15\right)}{35}=25\)
890 : x = 35 du 15
=> x = 890 : 35 + 15
x = \(\frac{178}{7}\) + 15
x = \(\frac{238}{7}\)
890 : x = 35 dư 15
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
tìm x biết 890:x=35 dư 15
Ta có: \(890:x=35\) (dư 15)
\(\Rightarrow\left(890-15\right):35=x\)
\(\Rightarrow875:35=x\)
\(\Rightarrow x=25\)
Vậy x = 25
890 : x = 35 dư 15
890 = 35x + 15
890 - 15 = 35x
875 = 35x
875 : 35 = x
=> x = 25
890:x= 35 dư 15
648-34*x =444
a) ( 509 + 355 ) : x = 840 : 35
b) 890 : x = 35 dư 15
a) ( 509 + 355 ) : x = 840 : 35
864 : x = 24
x = 864 : 24
x = 36
b) 890 : x = 35 dư 15
=> 890 : x - 15 = 35
