Tìm X: 2125 : x - 124 : x - x = 100
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
tìm x 125 x X - X x 47 = 25350 2125 : X = 100
125 . x - x . 47 = 25350
x . ( 125 - 47 ) = 25350
78x = 25350
=> x = 325
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
216 : x + 34 : x = 10
2125 : x - 125 : x = 100
216x+34x=10
250x=10
x=10/250 hay x =1/25
tìm x biết a)\(\frac{x-100}{24}+\frac{x-98}{26}+\frac{x-96}{28}=3\)
b)\(\frac{x-28-124}{2011}+\frac{x-124-2011}{28}+\frac{x-2011-28}{124}=3\)
a )
\(\Rightarrow\frac{x-100}{24}-1+\frac{x-98}{26}-1+\frac{x-96}{26}-1=0\)
\(\frac{x-124}{24}+\frac{x-124}{26}+\frac{x-124}{28}=0\)
\(\left(x-124\right)\left(\frac{1}{26}+\frac{1}{24}+\frac{1}{28}\right)=0\)
\(\Rightarrow x-124=0\Rightarrow x=124\)
b)
\(\frac{x-28-124}{2011}-1+\frac{x-124-2011}{28}-1+\frac{x-2011-28}{124}-1=0\)
\(\Rightarrow\frac{x-2163}{2011}+\frac{x-2163}{28}+\frac{x-2163}{124}=0\)
\(\left(x-2163\right)\left(\frac{1}{2011}+\frac{1}{28}+\frac{1}{124}\right)=0\)
=) x - 2163 =0
x= 2163
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
