tìm x nhé 

 

Answer 1

\(\left(9-2x\right)^3=5^3\\ 9-2x=5\\ -2x=5-9\\ -2x=-4\\ x=-4:\left(-2\right)\\ x=2\)

Answer 2

`(9-2x)^{3}=125=5^{3}`

`=>9-2x=5`

`=>2x=9-5=4`

`=>x=2`

Answer 3

`(9-2x)^3=125`

`=> (9-2x)^3=5^3`

`=> 9-2x=5`

`=>2x=9-5`

`=>2x=4`

`=>x=2`

Answer 4

(9-2x)=5

2x=9-5

x=4:2

x=2

Answer 5

(9-2x)³= 125

(9-2x)³= 5³

(9-2x) = 5

    2x = 9 - 5

    2x = 4

      x = 4 : 2

      x = 2
