A Court of Silver Flames (A Court of Thorns and Roses, 5) (A Court of Thorns and Roses, 4)

A Court of Silver Flames (A Court of Thorns and Roses, 5) (A Court of Thorns and Roses, 4)

Matematika |x + 7| = -4 mohon bantuannya

|x + 7| = -4 mohon bantuannya

|x + 7| = -4

Persamaan di atas tidak memiliki penyelesaian untuk x karena di ruas kanan adalah bilangan negatif (-4) padahal di ruas kiri ada nilai mutlak di mana nilainya harus positif.

Materi : Konsep Mutlak

|x + 7| = -4

(1) f(x) = -4

x + 7 = -4

x = - 7 - 4

[ x = -11 ]

(2) - f(x) = -4

-( x + 7 ) = -4

- x - 7 = -4

x = 4 - 7

[ x = -3 ]

Maka HP = { x | x = -3 atau x = -7 }

Semoga bisa membantu
