Answer 1

a - b = 45
a : b = 5 rest 5
a = 5×b+ 5 (conform T.I.R.)

a |___|___|___|___|___|+5
b |___|

5 segmente egale+5 - 1 segment egal = 4 segmente egale + 5 = 45
45 - 5 = 40
40 : 4 = 10 (un segment egal)
a = 5 × 10 + 5 = 55
b = 10

Verificare:
55 - 10 = 45
55 : 10 = 5 rest 5

Answer 2

a -b=45
a:b=5, rest 5
a=5xb+5

5b+5-b=45
4b+5=45
4b=45-5=40
b=40:4=10

b=10
a-b=45
a=45+10
a=55
