Tentukan nilai mutlak 1. |4+3x1|=1 2. 5|2x-1|+4=11 3. |5x+3|=|3x+5|

Nomor 1
|4 + 3x| = 1

4 + 3x = 1
3x = 1 - 4
3x = -3
x = -1

4 + 3x = -1
3x = -1 - 4
3x = -5
x = - 5/3

HP {-1 , -5/3}

Nomor 2
5|2x - 1| + 4 = 11
5|2x - 1| = 11 - 4
|2x - 1| = 7/5

2x - 1 = 7/5
2x = 7/5 + 1
2x = 12/5
x = 12/(5×2)
x = 6/5

2x - 1 = -7/5
2x = -7/5 + 1
2x = - 2/5
x = -2 /(5×2)
x = - 1/5

HP {6/5 , -1/5}

Nomor 3
|5x + 3| = |3x + 5|

5x + 3 = 3x + 5
5x - 3x = 5 - 3
2x = 2
x = 1

5x + 3 = -(3x + 5)
5x + 3 = -3x - 5
5x + 3x = -5 - 3
8x = -8
x = -1

HP {1 , -1}

Semoga berguna +_+
