Nilai Mutlak|5x + 3| = |3x + 5|
5x + 3 = 3x + 5
5x - 3x = 5 - 3
2x = 2
x = 1
5x + 3 = -(3x + 5)
5x + 3x = -5 - 3
8x = -8
x = -1
HP {1 , -1}
Semoga berguna +_+
|5x+3| |3x+5|
5x+3 = 0 3x+5 = 0
5x = -3 3x = -5
x = -3/5 x = -5/3
*) membuat interval
x < -5/3
-5/3 < x < -3/5
x > -3/5
*) menentukan persamaan interval
x < -5/3
|5x+3| = |3x+5|
-(5x+3) = 3x+5
-5x-3 = 3x+5
-5x-3x = 5+3
-8x = 8
x = -1
x > -3/5
|5x+3| = |3x+5|
5x+3 = 3x+5
5x-3x = 5-3
2x = 2
x = 1
