Question

A+B=28 a-B=2
A+b+c=33
A,B,C=NR CONSECUTIVE

A+B=36
B DE 3 ORI MAI MARE DECÂT A​

Answer 1

Prima problema:

a+b=28

a-b=2

a+b+c=33

a,b,c= numere consecutive

Daca a-b=2 <=> a=b+2

=>b+2+b=28

2b+2=28

2b=28-2

2b=26

b=26:2

b=13

a+13=28

a=28-13

a=15

15+13+c=33

28+c=33

c=33-28

c=5

*Nu se poate sa fie consecutive*

Problema 2:

a+b=36

b=3a

a+3a=36

4a=36

a=36:4

a=9

b=3•9

b=27
