Caro amigo :
Basta você seguir o sentido contrário das operações , tá ?
16 x 5 = 80
80 - 50 = 30
30 : 2 = 15
15 + 23 = 38
38 x 3 = 114
Em resumo , o número desejado é 114
------------------------------------------------------------------------------------
Verificação :
114 : 3 = 38 ----> 38-23 = 15 ---> 15X2=30 ---> 30+50=80 ---
> 80:5 = 16 .
Um abraço !!!

((x/3-23)*2+50)/5=16
x = ((16*5-50)/2+23)*3
x = 114

(23 - x/3) * 2 + 50 : 5 = 16
(69 - x)/3 * 2 + 50 : 5 = 16
(138 - 2x)/3 + 10 = 16
(138 - 2x)/3 = 16 - 10
(138 - 2x)/3 = 6
138 - 2x = 6 * 3
-2x = 18 - 138
x = -120/-2
x = 60
Resposta: 60.

Fiz as operações de trás pra frente e deu certo igual à do Carlos.
16 x 5 = 80
80 - 50 = 30
30 : 2 = 15
15 + 23 = 38
38 x 3 = 114
o número é 114
Prova :
114 : 3 = 38 -> 38-23 = 15-> 15X2=30 -> 30+50=80 ---
> 80:5 = 16 .

Vamos lá:
transformando em sentença matemática, temos:
{ x / 3 - 23.(2) + 50} / 5 = 16
{ x / 3 - 46 + 50 } / 5 = 16
{ x / 3 + 4 } / 5 = 16
{ ( x + 12) / 3} / 5 = 16
( x + 12) 3 .(5) = 16
5x +12(5) = 16(3)
5x + 60 = 48
5x = 48 - 60
5x = - 12
x = - 12 / 5
x = - 2,4

suponha que seja x esse numero, assim:
{[(x/3) - 23]*2 + 50}/5 = 16
[(x/3) - 23]*2 + 50 = 16*5
[(x/3) - 23]*2 = 80 - 50
[(x/3) - 23]*2 = 30
(x/3) - 23 = 30/2
x/3 = 15 +23
x/3 = 38
x = 38*3
x = 114
espero ter resolvido seu problema

O número que você está procurando é o tal de X.
((23 -X/3).2+50)/5=16
(23-X/3).2+50=5.16
(23-X/3)=(5.16-50)/2
(23-X/3)=15
23-15=X/3
8.3=X
X=24
