Question

Tìm x,biết: 

a)2x+4(x-2)=5

Answer 1

2x + 4 (x - 2) = 5

=> 2x + 4x - 8 = 5

=> 6x - 8 = 5

=> 6x = 13

=> x = \(\dfrac{13}{6}\)

Answer 2

<=> 2x + 4x - 8 = 5

<=> 6x = 5 + 8

<=> 6x = 13

<=> x = 13/6

Vậy ..

Answer 3

`2x + 4(x - 2)  =5`

`2x + 4x - 8  =5`

`(2 + 4) x - 8 =5`

`6x - 8 =5`

`6x = 13`

`x = 13 : 6`

`x  = 13/6`

Answer 4

`2x + 4(x-2) = 5`

`=> 2x + 4x - 8 = 5`

`=> 6x - 8 = 5`

`=> 6x       = 5 + 8`

`=> 6x       = 13`

`=> x         = 13 : 6`

`=>` \(x=\dfrac{13}{6}\)
