Question

Tìm x:  3/7 * x = 4/3 + 2/3

Answer 1

: `a) x : 3/8 = 1/6`
`=>x=1/6xx3/8`
`=>x=1/16`
Vậy `x=1/16` `
` b) 3/7xx x = 4/3 + 2/3`
`=>3/7xx x=6/3=2`
`=>x=2:3/7`
`=>x=14/3`
Vậy `x=14/3`

Answer 2

`a) x : 3/8 = 1/6`
`=>x=1/6xx3/8`
`=>x=1/16`
Vậy `x=1/16` 
` b) 3/7xx x = 4/3 + 2/3`
`=>3/7xx x=6/3=2`
`=>x=2:3/7`
`=>x=14/3`
Vậy `x=14/3`

Answer 3

x : 3/8=1/6

x= 1/6 x 3/8 

x= 3/48

B) 3/7 : x = 4/3+2/3

3/7 : x = 6/3

x= 6/3 x 3/7 

=18/21

Answer 4

Ta có: \(\dfrac{3}{7}\cdot x=\dfrac{4}{3}+\dfrac{2}{3}\)

\(\Leftrightarrow x\cdot\dfrac{3}{7}=2\)

hay \(x=\dfrac{14}{3}\)

Vậy: \(x=\dfrac{14}{3}\)
