Question

1/2 x - 4/7 = 1 3/7

Answer 1

`1/2x - 4/7 = 1 3/7`
`=>1/2x-4/7=10/7`
`=>1/2x=10/7+4/7=2`
`=>x=4`
Vậy `x=4`

Answer 2

Ta có: \(\dfrac{1}{2}x-\dfrac{4}{7}=1\dfrac{3}{7}\)

\(\Leftrightarrow x\cdot\dfrac{1}{2}=\dfrac{10}{7}+\dfrac{4}{7}=2\)

hay x=4

Vậy: x=4

Answer 3

4

Answer 4

\(\dfrac{1}{2}x-\dfrac{4}{7}=1\dfrac{3}{7}\) 

        \(\dfrac{1}{2}x=\dfrac{10}{7}+\dfrac{4}{7}\) 

         \(\dfrac{1}{2}x=2\) 

            \(x=2:\dfrac{1}{2}\) 

            \(x=4\)

Answer 5

x=4
