10 chia hết cho 3x + 1

=> \(3x+1\inƯ\left(10\right)=\left\{1;2;5;10;-1;-2;-5;-10\right\}\)

=> 3x + 1 = 1 => 3x = 0 => x = 0

3x + 1 = 2 => 3x = 1 => x = 1/3

3x + 1 = 5 => 3x = 4 => x = 4/3

3x + 1 = 10 => 3x = 9 => x = 3

3x + 1 = -1 => 3x = -2 =>x = -2/3

3x + 1 = -2 => 3x = -3 => x = -1

3x + 1 = -5 => 3x = -6 => x = -2

3x + 1 = -10 => 3x = -11 => x = -11/3

Vậy x = 0 ; x = 1/3; x = 4/3; x = 3; x = -2/3; x = -1; x = -2; x = -11/3
