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 - x . 47 = 25350
x . ( 125 - 47 ) = 25350
78x = 25350
=> x = 325
a,
2125:X-125:X=100
=>[2125-125]:X=100
=>2000:X=100
=>X=2000:100
=>X=20
Vậy X=20
a )
\(\Rightarrow\frac{x-100}{24}-1+\frac{x-98}{26}-1+\frac{x-96}{26}-1=0\)
\(\frac{x-124}{24}+\frac{x-124}{26}+\frac{x-124}{28}=0\)
\(\left(x-124\right)\left(\frac{1}{26}+\frac{1}{24}+\frac{1}{28}\right)=0\)
\(\Rightarrow x-124=0\Rightarrow x=124\)
a, X x 186-Z x 86=3400

a) \(x\times186-x\times86=3400\)
\(x\times\left(186-86\right)=3400\)
\(x\times100=3400\)
\(x=3400:100\)
\(x=34\)
b) \(x\times75+57\times x=32604\)
\(x\times\left(75+57\right)=32604\)
\(x\times132=32604\)
\(x=32604:132\)
\(x=247\)
