3885 : ( X x 31 ) = 37
Tìm x biết 3885 : ( x. 21 ) = 37
x . 21 = 3885 : 37
x . 21 = 105
x = 105 : 21
x = 5
x =5
chúc hk tốt
để 3885 : ( y x 21 ) = 37 thì y bao nhiêu ?
cả bài nha
yx21=3885:37
yx21= 105
x =105:21
x =5
ok :))
3885 : ( y x 21 ) = 37
y x 21 = 3885 : 37
y x 21 = 105
y = 105 : 21
y = 5
3885:(y x 21)=37
y x 21=3885:37
y x 21=105
y =105:21
y =5
Vậy y=5
Tìm x : a) 3885:(X * 21) =37. b) 162:x+216:x=6
a) 3885:(\(x\) x 21) =37.
(\(x\) x 21) = 3885 : 37
(\(x\) x 21) = 105
\(x\) = 105 : 21
\(x\) = 5.
Vậy \(x\) =5.
b) 162:x+216:x=6
(162 + 216) : x =6
378 : x = 6
x = 378 : 6
x = 63.
Vậy x = 63.
# HOK TỐT #
a) 3885:(X * 21) =37 b) 162:x+216:x=6
x . 21 = 3885 : 37 (162+216):x=6
x . 21 = 105 378:x=6
x= 105: 21 x = 378:6
x = 5 x = 63
Tìm x :
a) 3885:(x. 21) =37
x. 21 =3885:37
x. 21 =105
x =105:21
x =5
Vậy x = 5
b) 162:x+216:x=6
(162 + 216 ) : x = 6
378 : x = 6
x = 378 : 6
x = 63
Vậy x=63

@_@ k mình nha
Tìm X:
a) 3885 : ( X x 21 ) = 37
b) 50343 : X = 405 ( dư 123 )
a: =>x*21=3885:37=105
=>x=105:21=5
b: 50343:x=405 dư 123
=>x=(50343-123)/405=124
a, 3885 : (X x 21) = 37
=> 21X = 3885/37
=> 21X = 105
=> X = 5
b, 50343 : X = 405 (dư 123)
=> X = 50343 : 405 + 123
=> X = 33386/135
a) \(3885:\left(x\times21\right)=37\)
\(x\times21=3885:37\)
\(x\times21=105\)
\(x=105:21=5\)
b) \(50343:x=405\)(dư 123)
=> \(405\times x+123=50343\)
\(405\times x=50343-123\)
\(405\times x=50220\)
\(x=50220:405=124\)

a: =>21y=105
hay y=5

Ai giải được cho mình mình tick 1 đúng
X x 21 = 3885 : 37
X x 21 = 105
X = 105 : 21
X = 5
3885 : ( X x 21 ) = 37
X x 21 = 3885 : 37
X x 21 = 105
X = 105 : 21
X = 5
X x 21 = 3885 : 37
X x 21 = 105
X = 105 : 21
X = 5
c) Tìm số tự nhiên x, biết: ( 8705 + 5235 ) – 5x = 3885.
c) (8705 + 5235) – 5x = 3885
13940 – 5x = 3885
5x = 13940 – 3885
5x = 10055
x = 10055 : 5 = 2011
(8105 + 5435) - 5x = 3885 Tìm x của câu này giúp mik vs
