Penjelasan dengan langkah-langkah:

nilai mutlak

soal

|3x – 4| – x = 5

|3x – 4| =  x + 5

(3x – 4 + x +  5)(3x- 4- x – 5) = 0

(4x + 1)(2x – 9)= 0

8x² – 34x –  8 =0

x1 +x2 = – b/a

x1+ x2 = 34/8 =  17/4

cara lain  definisi

i) -(3x- 4) – x =  5

-3x  + 4 – x = 5

– 4x = 1

x= – 1/4

ii)  3x – 4 – x = 5

2x   = 9

x =  9/2

x1 +x2 =  - 1/4  +  9.2

x1+ x2 =  17/4
