nilai x yang memenuhi persamaan |6+2x|=4

di bagi maaf kalo salah

6+2x = 4
2x = 4 - 6
2x = -2
x = -2/2
x = -1.

uji. 6+2(-1) = 4
      6+-2 = 4
       6+-2-4 = 0
       6+ -6 = 0
        0 = 0

|6+2x| = 4
= 6+2x = -4        atau 6+2x = 4
      2x  = -4-6                 2x = 4-6
      2x  = -8                    2x = -2
       x   = -8/2                   x = -2/2
       x   = -4                      x = -1.
