|3x+1|>10
tolong dijawab yah kak​

|3x+1| > 10

3x + 1 > 10 3x + 1 > -10

3x > 10 - 1 3x > -10 - 1

3x > 9 3x > -11

x > 9/3 x < -11/3

x > 3 x = {..., ..., -13/3 -12/3}

x = {4, 5, 6, ..., ...}

HP {x < -11/3, x > 3}

| 3x + 1 | > 10

  • Penyelesaian pertama

3x + 1 > 10

3x > 10 - 1

3x > 9

x > 9 ÷ 3

x > 3

  • Penyelesaian kedua

- ( 3x + 1 ) < 10

Kalikan kedua ruas dengan -1 dan balikkan tanda

3x + 1 < -10

3x < -10 - 1

3x < -11

x < -11/3

[tex] \\ [/tex]

Sehingga :

  • x < -11/3
  • x > 3

Semoga Membantu
