Question

Suma a doua nr este 150. Daca impartim nr mare la cel mic obtin catu 4 si restul 15. Aflati numerele

Answer 1

a+b=150
a:b=4 rest 15 ⇒ a=4xb+15
4b+15+b=150
4b+b=150-15
5b=135
b=135:5
b=27
a=4x27+15
a=108+15
a=123
V: 123+27=150

Answer 2

a = primul nr
b = al doilea nr 
a + b = 150 
a : b = 4, r 15=> a = 4b +15
4b+15 + b = 150
5b=150-15
5b= 135
b=135:5
b= 27
a=27x4+ 15
b=96+15
b=111
