Penyelesaian dari nilai mutlak linear satu variabel 1. |x-2| + |x+4|= 7 2. |3x+1| + |2x-3| =5 TOLONG BESOK DIKUMPULKAN PLEASE..

1•
|x - 2| + |x + 4| = 7
•
x - 2 + x + 4 = 7
2x = 7 - 2
x = 5/2

•
x - 2 + x + 4 = -7
2x = -9
x = -9/2

2•
|3x + 1| + |2x - 3| = 5
•
5x - 2 = 5
x = 7/5

•
5x - 2 = -5
x = -3/5
