Bab Persamaan LInear

(1/2) . (2x + 1) - 2/3 = (1/3) . (x - 2)

** dikali 6 **

3 (2x + 1) - 4 = 2 (x  - 2)
6x + 3 - 4 = 2x - 4
6x - 2x = -4 + 1
4x = -3
x = -3/4

x + 1 
= -3/4 + 4/4
= 1/4

≡ penyelesaian :

⇒½ ( 2x + 1 ) - 2 / 3 = 1 / 3 × ( x - 2 )
--------------------------------------------------- ( kali 6 agar penyebut hilang )

⇒3 ( 2x + 1 ) - 4 = 2 ( x - 2 )
⇒6x + 3 - 4 = 2x - 4
⇒6x - 2x = - 4 - 3 + 4
⇒4x = -3
⇒x = -¾

maka, nilai x + 1 :
⇒x + 1
⇒-¾ + 1
⇒-¾ + 4 / 4
⇒¼
