Nilai x dari persamaan:-2|x+3|+5=-8 adalah?

Kelas 10 Matematika
Bab Nilai Mutlak

-2 | x + 3 | + 5 = -8
- 2 | x + 3 | = -8 - 5
| x + 3 | = -13/-2
| x + 3 | = 13/2

x + 3 = 13/2
x = 13/2 - 3
x = 13/2 - 6/2
x = 7/2

x + 3 = -13/2
x = -13/2 - 3
x = -13/2 - 6/2
x = -19/2

-2(x+3)+5=-8
-2x-6=-8-5
-2x=-12+6
-2x=-12
x=6
