Question

54 - 4 x [ 99 + (95 + x : 5 : 3 ) : 100 ] : 8 = 4

Answer 1

54-4×[99+(95+X:5:3):100]:8 = 4
4×[99+(95+X:5:3):100]:8 = 54-4
4×[99+(95+X:5:3):100] = 50×8
99+(95+X:5:3):100= 400:4
(95+X:5:3):100 = 100-99
95+X:5:3 = 1×100
X:5:3 = 100-95
X:5:3 = 5
X:5 = 5×3
X:5 = 15
X = 15×5
X = 75
Verificare:
95+75:5:3 = 95+ 5 = 100
100:100= 1
99+1 = 100
4×100 = 400
400:8 = 50
54-50 = 4
