x : 2 + x + x : 3 + x : 4 = 26
x : ( 2 + 1 + 3 + 4 ) = 26
x : 10 = 26
x = 26 x 10
x = 260
X : 2 + X + X : 3 + X : 4 = 26
X : (2 + 3 + 4 + 1) =26
X :10 =26
X =26 x 10
X =260
Vậy X = 260
Chúc bạn học tốt
X : 2 + X + X : 3 + X : 4 = 26
\(X\times\frac{1}{2}+X+X\times\frac{1}{3}+X\times\frac{1}{4}=26\)
\(X\times\left(\frac{1}{2}+1+\frac{1}{3}+\frac{1}{4}\right)=26\)
\(X\times\frac{25}{12}=26\)
\(X=12,48\)
X : 2 + X + X : 3 + X : 4 = 26
X : ( 2 + 1 + 3 + 4 ) = 26
X : 10 = 26
X = 26 x 10
X = 260 nha bạn
x : 2 + x + x : 3 + x : 4 = 26
x : 2 + x : 1 + x : 3 + x : 4 = 26
x : ( 2 + 1 + 3 + 4 ) = 26
x : 10 = 26
x = 26 x 10
x = 260
x : 2 + x + x : 3 + x : 4 = 26
x : (2 + 3+4+1) = 26
x : 10 = 26
x =26x10=260
X : 2 + X + X : 3 + X : 4 = 26
X : ( 2 + 1 + 3 + 4 ) = 26
X : 10 = 26
X = 26 x 10 = 260
