Question

3 intregi x/3- 7/3 =1 intreg 1/3

Answer 1

Rezolvi exercitiul pe baza formulei:
 a intregi si b/c= (a*c+b)/c
Deci:
3 intregi si x/3 -7/3= 1 intreg si 1/3 ;  (3*3+x)/3 -7/3 = (1*3+1)/3 ;    (9+x-7)/3= 4/3 ;  9+x-7=4 ; 2+x=4 ;  x=4-2;  x=2

Answer 2

 a intregi si b/c= (a*c+b)/c
Deci:
3 intregi si x/3 -7/3= 1 intreg si 1/3 ;  (3*3+x)/3 -7/3 = (1*3+1)/3 ;    (9+x-7)/3= 4/3 ;  9+x-7=4 ; 2+x=4 ;  x=4-2;  x=2
