nilai x yang memenuhi persamaan |3x-2| - |x-3| = 4 - |x+2| adalah.....

|3x-2| - |x-3| = 4 - |x+2|, utk x > 2/3
3x - 2 - x + 3 = 4 - x - 2
3x - x + x - 2 + 3 - 4 + 2 = 0
3x - 1 = 0
3x = 1
x = 1/3

-3x + 2 - x + 3 = 4 - x - 2, utk x < 2/3
-3x - x + x + 2 + 3 - 4 + 2 = 0
-3x + 3 = 0
-3x = -3
x = 1

HP : { x = 1/3, x = 1}
