Tentukan nilai mutlak dari 1. |x-3| + |2x-8| = 7 2. |5x+3| = 2x-6 3. 4 |3x+2| = 6 4. |5x+2| - 6 = 10x + 12

1. ×-3 + 2×-8=7
×-2×+8+3=7
3× + 11 = 7
14x=7
X=7/14
=2

2. 5X+3= 2X-6
5X+2x = - 3-6
7x = 9
X 9/7
Kalau gak salah

1.X + 3+ 2x - 8=7
X + 2x=7 -3 +8
3x=12
X=4
-x-3-2x+8=7
-x-2x=7+3-8
-3x=2
x=2/-3
2. 5x+3= 2x-6
5x- 2x=-6-3
-3x=-9
X=3
3. 12x+ 8=6
12x=-2
X= -2per12
x=-1per6
4. 5x + 2- 6= 10x + 12
5x-10x=12-2+ 6
- 5x=16
x= 16 per - 5
smoga bermanfaat!!!Maaf gk sma cara negatifnya.
