Пошаговое объяснение:
а)
|8х - 2| = 6
1)
8х - 2 = -6
8х = -6 + 2
8х = -4
х = -4 : 8
х1 = -0,5
2)
8х - 2 = 6
8х = 6 + 2
8х = 8
х = 8 : 8
х2 = 1
б)
(х + 5)(3х - 12) = 0
х + 5 = 0
х1 = -5
3х - 12 = 0
3х = 12
х = 12 : 3
х2 = 4
в)
|4х - 5| / 3 = 2
|4х - 5| = 2 * 3
|4х - 5| = 6
4х - 5 = -6
4х = -6 + 5
4х = -1
х = -1 : 4
х1 = -0,25
4х - 5 = 6
4х = 6 + 5
4х = 11
х = 11 : 4
х2 = 2,75
