Answer 1

Răspuns:

4 × | 2 x | - 7,1(6) = 5 / 3 × | 2x | - 1 / 6

4 × 2 × | x | - 43 / 6 = 5 / 3 × 2 × | x | - 1 / 6

8 × | x | - 43 / 6 = 10 / 3 × | x | - 1 / 6

48 × | x | - 43 = 20 × | x | - 1

48 × | x | - 20 × | x | = - 1 + 43

28 × | x | = 42

| x | = 3 / 2

x = 3 / 2

x = - 3 / 2

x1 = - 3 / 2 ; x2 = 3 / 2

x ∈ { - 3 / 2 , 3 / 2 }
