Question

Suma a doua numere este88.Determinati numerele stiind ca impartindu-l pe cel mare la cel mic obtine catul4 si restul 13

Answer 1

a + b = 88
a : b = 4 rest 13
a = 4 b + 13
4b + 13 + b = 88
5b = 88 - 13
5b = 75
b = 75 : 5
b = 15
a = 4 x 15 + 13
a = 60 + 13 
a= 73
verificam
73 + 15 = 88

Answer 2

a:b=4 rest 13=> a=4b +13
inlocuim:
4b+13 +b+88
5b+13=88
5b+88-13
5b+75=>b=75:5=>b=15
a=4b+13
a=4 x 15 +13
a=60+13
a=73
