`430 + 35,2 = (x-9) . 25`

`=> 430 + 35,2 = (x-9) . 25`

`=> 465,2 = (x-9) . 25`

`=> x - 9 =  465,2  : 25`

`=> x - 9 = 2326/125`

`=> x = 2326/125 + 9`

Do `9 ∈ N, 2326/125 ∉ N`

`=> 2326/125 + 9 ∉ N`

Hay `x ∉ N`

Vậy không tồn tại số tự nhiên `x` thỏa mãn ycbt

`x-18-(6320:1580,25) = 300`

`=> x-18-(6320:1580,25) = 300`

`=> x - 25280/6321 = 300 + 18`

`=> x - 25280/6321 = 318`

`=> x = 25280/6321 + 318`

Do `25280/6321 ∉ N, 318 ∈ N`

`=> 25280/6321 + 318 ∉ N`

Hay `x ∉ N`

Vậy không tồn tại số tự nhiên `x` thỏa mãn `ycbt`

(3x+1).9-74=16

(3x+1).9=16+74
