Răspuns:
nu stiu prin metoda figurativa , dar
x- timbre, a- nr pagini
x:a= 6 rest 6
x:(a-1)=8
x=6a+6
(6a+6):(a-1)=8
6a+6=8(a-1)
6a+6= 8a-8
8a-6a=8+6
2a=14
a=7
inlocuim la x=6a+6
x=49
sau:
p = numarul de pagini
t = numarul de timbre
8 × ( p - 1) = 6 × p + 6
8 × p - 8 = 6 × p + 6
8 × p - 6 × p = 6 + 8
2 × p = 14
p = 14 : 2
p = 7 (pagini )
________
6 × 7 + 6 = 42 + 6 = 48 (timbre)
