Question

tìm x

 

Answer 1

\(\dfrac{x}{2}=\dfrac{x+2}{3}\)
\(x.3=\left(x+2\right).2\)
\(x.3=2x+2.2\)
\(x.3=2x+4\)
\(3x-2x=4\)
\(x\left(3-2\right)=4\)
\(x1=4\)
\(x=4:1\)
\(x=4\)
Vậy \(x=4\)

Answer 2

\(\dfrac{x}{2}=\dfrac{x+2}{3}\)

=>3x=2(x+2)

=>3x=2x+4

=>x=4

Answer 3

` x/2 = (x+2)/3 `

 

` 3x = 2.(x+2)`

` 3x = 2x + 4`

` x = 4`

Answer 4

`x/2 + (x+2)/3`

 

` 3x = 2.(x+2)`

 

` 3x = 2x + 4`

 

` x = 4`

 

Vậy `x=4`
