Tentukan nilai x dari persamaan linier nilai mutlak berikut
a. |2x| - |x - 2| = 0
b. |x| + |x - 1| = 0
c. |-4| X |5x + 6| = |10x - 8| per 2
d. 2x + |8 - 2x| = |x - 4|
e. |2x| - |x - 3| + |2x + 1| = 0
f. 5 |2x - 3| = 2 |3 - 5x|
a. |2x| - |x - 2| = 0
b. |x| + |x - 1| = 0
c. |-4| X |5x + 6| = |10x - 8| per 2
d. 2x + |8 - 2x| = |x - 4|
e. |2x| - |x - 3| + |2x + 1| = 0
f. 5 |2x - 3| = 2 |3 - 5x|

1. Jawaban Darksimple
a |2x| - |x - 2| = 0
2x - x - 2 = 0
x - 2 = 0
x = 0 + 2
x = 2
b |x| + |x - 1| = 0
x + x - 1 = 0
2x - 1 = 0
2x = 0 + 1
2x = 1
x = ½
