[(n - 5) : 3 + 44)] × 2 = 120
(n - 5) : 3 + 44 = 120 : 2
(n - 5) : 3 + 44 = 60
(n - 5) : 3 = 60 - 44
(n - 5) : 3 = 16
n - 5 = 16 × 3
n - 5 = 48
n = 48 + 5
n = 53 (numarul)
(n - 5) : 3 + 44 = 120 : 2
(n - 5) : 3 + 44 = 60
(n - 5) : 3 = 60 - 44
(n - 5) : 3 = 16
n - 5 = 16 × 3
n - 5 = 48
n = 48 + 5
n = 53 (numarul)
