Question

Tentukan HP dari
1.|2x+5|=-2
2.|4x-6|=7
3.|2x-1|=1
Tolong jawab yaaa

Answer 1

2X+5=2x+5 Karena tidak bisa dijumlah.

Answer 2

1 |2x + 5| = -2
2x + 5 = -2
2x = -2 - 5
2x = -7
x = -7/2
2x + 5 = 2
2x = 2 - 5
2x = -3
x = -3/2
HP = {-7/2, -3/2}
2 |4x - 6| = 7
4x - 6 = 7
4x = 7 + 6
4x = 13
x = 13/4
4x - 6 = -7
4x = -7 + 4
4x = -3
x = -3/4
HP = {-3/4, 13/4}
3 |2x - 1| = 1
2x - 1 = 1
2x = 1 + 1
2x = 2
x = 1
2x - 1 = -1
2x = -1 + 1
2x = 0
x = 0
HP = {0, 1}
