Răspuns :
a : 75 = x ==> a = 75x
b : 75 = x + 1 ==> b = 75x + 75
a + b = 12 675
75x + 75x + 75 = 12 675
150x = 12 676 - 75
150x = 12 600
x = 12 600 : 150
x = 84
a = 75 × 84 = 6 300
b = 75 × 84 + 75 = 6300+75 = 6375
Verificare:
6300 + 6375 = 12 675
b : 75 = x + 1 ==> b = 75x + 75
a + b = 12 675
75x + 75x + 75 = 12 675
150x = 12 676 - 75
150x = 12 600
x = 12 600 : 150
x = 84
a = 75 × 84 = 6 300
b = 75 × 84 + 75 = 6300+75 = 6375
Verificare:
6300 + 6375 = 12 675
