Notam a si b cele doua numere
a+b = 5 068
a-b = 432 => a = b+432
a |______|+432
b |______|
avem 2 segmente egale +432 = 5 068
5 068-432 = 4 636
4 646:3 = 2 318 (un segment)
a = 2 318+432 = 2 750
b = 2 318
Verificare:
2 750+ 2 318 = 5 068
2 750 - 2 318 = 432
a = 2 750
b = 2 318
2) b+432+b = 5 068
2×b+432 = 5 068
2×b = 5 068-432
2×b = 4 636 |:2
b = 2 318
a = 5 068-2 318
a = 2 750
