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!
890/x=35dư15
Theo đề bài, ta có:
(890 - 15) : x =35
875 : 35 = x
\(\Rightarrow\)x =25
Vậy , x = 25
890/x = 35 dư 15
=> 890 : x = 35 dư 15
=> 875 : x = 35
=> x = 875 : 35
=> x = 25
x+375=890
890-375=515 tk cho mk nhiều nhiều nha hihihi
(5x - 36) : 18 = 12
(x -890) . (74 - x) = 0
1) \(\Rightarrow5x-36=216\)
\(\Rightarrow5x=252\Rightarrow x=\dfrac{252}{5}\)
2) \(\Rightarrow\left[{}\begin{matrix}x-890=0\\74-x=0\end{matrix}\right.\)\(\Rightarrow\left[{}\begin{matrix}x=890\\x=74\end{matrix}\right.\)
(5x-36):18=12
5x-36=216
5x=252
x=50,4
(x-890)(74-x)=0
=> x-890=0 hoặc 74-x=0
x=890 hoặc x=74
120+x=890-90
120 + x = 890 - 90
120 + x = 800
x = 800 - 120
x = 680
120+x=890-90
120+x=800
x=800-120
x=680
2222 x 5 : 8 + 890 - 2278=
1. 890 : x =35 dư 15
Lời giải:
$890=x\times 35+15$
$890-15=x\times 35$
$875=x\times 35$
$x=875:35=25$
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
