Ответ:

x1 = 1

x2 = -1

x3 = 1/2

x4 = -1/2

Пошаговое объяснение:

|2|x| - 3/2| = 1/2

2|x1| - 3/2 = 1/2

2*x1 - 3/2 = 1/2

2*x1 = 4/2

x1 = 1

2*(-x2) - 3/2 = 1/2

-2*x2 = 4/2

x2 = -1

-(2*x3 - 3/2) = 1/2

-2*x3 + 3/2 = 1/2

-2*x3 = -1

x3 = 1/2

-(-(2x4) - 3/2) = 1/2

2x4 + 3/2 = 1/2

2x4 = -1

x4 = -1/2
