1) (3x-1)(x+1)(2x+3) = 0
Решим уравнение по отдельности:
3x - 1 = 03x = 1x = 1/3
x + 1 = 0x = -1
2x + 3 = 02x = -3x = -3/2
Ответ: x = 1/3, x = -1, x = -3/2
2) |3x + 1| = 2
3x + 1 = 23x = 1x = 1/3
3x + 1 = -23x = -3x = -1
Ответ: x = 1/3, x = -1
3) |3 - 4x| = 3x - 2
3 - 4x = 3x - 27x = 5x = 5/7
3 - 4x = - (3x - 2)3 - 4x = -3x + 27x = -1x = -1/7
Ответ: x = 5/7, x = -1/7

2x = -3
x = -3/2
Ответ: x = 1/3, x = -1, x = -3/2
2) |3x + 1| = 2
3x + 1 = 2
3x = 1
x = 1/3
3x + 1 = -2
3x = -3
x = -1
Ответ: x = 1/3, x = -1
3) |3 - 4x| = 3x - 2
3 - 4x = 3x - 2
7x = 5
x = 5/7
3 - 4x = - (3x - 2)
3 - 4x = -3x + 2
7x = -1
x = -1/7
Ответ: x = 5/7, x = -1/7
