peraamaan nilai mutlak linear satu variabel (x+2)+(3)+(2x-5)=8

Mapel : Matematika
Kelas : X SMA
Bab : Mutlak

Pembahasan :
|x + 2| + |3| + |2x - 5| = 8
|x + 2| + |2x - 5| = 5

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

x + 2 + 2x - 5 = -5
3x - 3 = -5
3x = -2
x = -2/3

(× + 2) + (3) + (2 × - 5) = 8
(× + 2) + (2× - 5 ) = 5

× + 2 + 2 × - 5 = 5
3× - 3 = 5
3× = 8
× = 8/3

× + 2 + 2× - 5 = -5
3× - 3
3× -2
× = -2/3

semoga membantu ya ☺
