Tentukan nilai dari | a + x | = 3
_________
P
Penjelasan dengan langkah-langkah:
4x = 2x + 4
4x – 2x = 4
2x = 4
x = 4/2
x = 2
a = 2
| a + x | = 3
l 2 + x l = 3
2 + x = 3
x = 3 – 2
x = 1
2 + x = -3
x = -3 – 2
x = -5
HP = {1, -5}
Jawaban:
4x = 2x + 4
4x – 2x = 4
2x = 4
a = 4/2
a = 2
| a + x | = 3
| 2 + x | = 3
2 + x = 3
x = 3 – 2
x = 1
2 + x = -3
x = – 3 – 2
x = –5
