Question

Tìm x , biết :

\(x\times6+x\div3=\frac{1}{2}\)

Ai nhanh mk tk

Answer 1

X x 6 + X x 1/3 = 1/2

X x ( 6 + 1/3 ) = 1/2

X x 19/3 = 1/2

X = 1/2 : 19/3

X = 3/38 

MK k bt có đúng k vì k dùng máy tính nếu đúng tích mk sai thì thôi các bạn thông cảm !!

Answer 2

\(x\cdot6+x:3=\frac{1}{2}\)

\(x\cdot6+x\cdot\frac{1}{3}=\frac{1}{2}\)

\(x\cdot\left(6+\frac{1}{3}\right)=\frac{1}{2}\)

\(x\cdot\frac{19}{3}=\frac{1}{2}\)

\(x=\frac{1}{2}:\frac{19}{3}\)

\(x=\frac{3}{38}\)

Answer 3

\(x\cdot6+x:3=\frac{1}{2}\)

\(=>x\cdot6+x\cdot\frac{1}{3}=\frac{1}{2}\)

\(=>x\cdot\left(6+\frac{1}{3}\right)=\frac{1}{2}\)

\(=>x\cdot\frac{19}{3}=\frac{1}{2}\)

\(=>x=\frac{1}{2}:\frac{19}{3}\)

\(=>x=\frac{1}{2}\cdot\frac{3}{19}\)

\(=>x=\frac{3}{38}\)

Answer 4

(6+3)x X = \(\frac{1}{2}\)

9 x X = \(\frac{1}{2}\)

X       = \(\frac{1}{2}\): 9

X       = \(\frac{1}{18}\)

Answer 5

\(x\times6+x\div3=\frac{1}{2}\)

<=> \(x\times6+x\times\frac{1}{3}=\frac{1}{2}\)

<=> \(x\times\left(6+\frac{1}{3}\right)=\frac{1}{2}\)

<=> \(x\times\frac{19}{3}=\frac{1}{2}\)

<=> \(x=\frac{1}{2}\div\frac{19}{3}=\frac{1}{2}\times\frac{3}{19}=\frac{3}{38}\)

Answer 6

x.6+x:3=1/2

x.6+x/3=1/2

36.x+2.x=3

38.x=3

x=3/38

Answer 7

\(x.6+x:3=\frac{1}{2}\)

\(\Rightarrow x.6+x.\frac{1}{3}=\frac{1}{2}\)

\(\Rightarrow x.\left(6+\frac{1}{3}\right)=\frac{1}{2}\)

\(\Rightarrow x.\frac{19}{3}=\frac{1}{2}\)

\(\Rightarrow x=\frac{3}{38}\)

Answer 8

3/38 nha phương anh
