Question

Matematika kls 10 minta tolong dong dengan caranya saya bingung banget...

Answer 1

Pembahasan

Nomor 1)

|x + 5| = 4

*) x + 5 = 4 → x = 4 - 5 = -1
**) x + 5 = -4 → x = -4 - 5 = -9

Hp = {-9, -1}


Nomor 2)

|5 - x| = 3

*) 5 - x = 3 → x = 5 - 3 = 2
**) 5 - x = -3 → x = 5 + 3 = 8

HP = {2, 8}



Nomor 3)

|2x + 3| = 5

*) 2x + 3 = 5 → x = 2/2 = 1
**) 2x + 3 = -5 → x = -8/2 = -4

HP = {-4, 1}
