penyelesaian dari persamaan |2x+4|+8=14 adalah

2x + 4 +8=14
2x=14-12
2x=2
x=1

I2x + 4 I + 8 = 14
I2x + 4 I = 6

(2x + 4) = 6                        atau               ( 2x + 4 ) = -6
(2x) = 2                                                     (2x )   = -10
x = 1                                                              x = -5

 Hp = {1 , -5 }
