Tolong bantu no 2 dari d sampai f​

Penjelasan dengan langkah-langkah:

D.

-4|x + 2| + 5 = -7

-4|x + 2| = -7 - 5

-4|x + 2| = -12

|x + 2| = 3

x + 2 = -3 atau x + 2 = 3

x = -3 - 2 atau x = 3 - 2

x = -5 atau x = 1

E.

|3x + 1| = |2x + 4|

3x + 1 = -2x - 4 atau 3x + 1 = 2x + 4

3x + 2x = -4 - 1 atau 3x - 2x = 4 - 1

5x = -5 atau 1x = 3

x = -1 atau x = 3

F.

6|2x - 3| = 3|3 - 2x|

6(2x - 3) = -3(3 - 2x) atau 6(2x - 3) = 3(3 - 2x)

12x - 18 = -9 + 6x atau 12x - 18 = 9 - 6x

12x - 6x = -9 + 18 atau 12x + 6x = 9 + 18

6x = 9 atau 18x = 27

x = 3/2 atau x = 3/2

x = 3/2
