Răspuns:

3 / 2 × | x - 3 / 2 | = 5 / 3 × | x - 3 / 2 | - 8 / 5

45 × | x - 3 / 2 | = 50 × | x - 3 / 2 | - 48

45 × | x - 3 / 2 | - 50 × | x - 3 / 2 | = - 48

- 5 × | x - 3 / 2 | = - 48

| x - 3 / 2 | = 48 / 5

x - 3 / 2 = 48 / 5 => x = 48 / 5 + 3 / 2 => x = 111 / 10

x - 3 / 2 = - 48 / 5 => x = - 48 / 5 + 3 / 2 => x = - 81 / 10

x1 = - 81 / 10 ; x2 = 111 / 10

x ∈ { - 81 / 10 ; 111 / 10 }
