Question

TÍNH

260 : ( x + 4 ) = 5( \(2^3+5\) ) - 3 ( \(3^2+2^2\))

Answer 1

`260:(x+4)=5.(2^3+5)-3.(3^2+2^2)`

`=> 260 : (x+4) = 5(8+5) - 3(9+4)`

`=> 260 : (x+4) = 5.13 - 3.13`

`=> 260:(x+4) = 13.(5-3)`

`=> 260:(x+4) = 13.2`

`=> 260:(x+4)=26`

`=>(x+4)=260:26`

`=>x+4-10`

`=>x=10-4`

`=>x=6`

Answer 2

=>260:(x+4)=5(8+5)-3(9+4)

=>260:(x+4)=26

=>x+4=10

=>x=6
