tìm x 125 x X - X x 47 = 25350 2125 : X = 100
Bài 2: Tìm x
a, 125 x X - X x 47 = 25350
b, 3978 : X - 987 : X = 100
(125 - 47) . x = 25350
78 . x = 25350
x = 325
3978 : x - 987 : x = 1003978 . 1/x - 987 . 1/x = 100
(3978 - 987) . 1/x = 100
2991 . 1/x = 100
1/x = 100/2991
x = 2991/100

A) 125 * X - X * 47 = 25350
=> X * (125 - 47) = 25350
=> X * 78 = 25350
=> X = 25350 : 78 = 325
Tìm X
125*X_X*47= 25350
\(125\times x-x\times47=25350\\x\times(125-47)=25350\\x\times78=25350\\x=25350:78\\x=325\)
125 × x - x 47 = 25350
x x [125 - 47] = 25350
x x 78 = 25350
x= 25350 : 78
x= 325
\(125\times x-x\times47=25350\)
\(=x\times\left(125-47\right)=25350\)
\(=x\times78=25350\)\(\Rightarrow x=25350\div78=325\)
Vậy \(x=325\)
Tìm X biết 2125 : X - 125 : X = 100
2125 : X - 125 : X = 100
<=> ( 2125 - 125 ) : X = 100
<=> 2000 : X = 100
=> X = 2000 : 100
X = 20
2125:X-125:X
=>(2125-125):X=100
=>2000:X =100
=>X =2000:100
=>x =20
125:x+100=125
trả lời nhanh giúp em
216 : x + 34 : x = 10
2125 : x - 125 : x = 100
216x+34x=10
250x=10
x=10/250 hay x =1/25
Tìm x:
a, 2125 : x - 125 : x = 100
(2125-125):x=100
2000:x=100
x=2000:100
x=20
a,
2125:X-125:X=100
=>[2125-125]:X=100
=>2000:X=100
=>X=2000:100
=>X=20
Vậy X=20
Tìm X: 2125 : x - 124 : x - x = 100
Tính giá trị của X
(X : 10) + 37 = 60
25 x X – 15 x X = 72
138 – ( X x5) = 38
(X x 9) : 52 = 18
52 x X + 48 x X = 100
623 x X – 123 x X = 1000
X x 16 + 84 x X = 700
236 x X – X x 36 = 2000
216 : X + 34 : X = 10
2125 : X – 125 : X = 100
Hô nhiều nhưng cố lên các bn ơi các bn sẽ làm được mà
Bạn ghi rõ dấu nhân với x ra , mk chẳng phân biệt đc
