Question

Va rog am nevoie urgent!!!

Answer 1

2*100+10a+b+100b+3*10+a+100a+10b+4=567
234+111a+111b=567
111(a+b)=567-234
111(a+b)=333
a+b=333/111
a+b=3
ab divizibil cu 3 daca a+b=3
1) a=2 si b=1=>221+132+214=567 (adevarat) (2;1)

2) a=1 si b=2=>212+231+124=567 (adevarat) (1;2)

3) a=0 si b=3 (nu convine)

4) a=3 si b=0 (nu convine)

5) a=2 si b=4=>224+432+244=900 (nu convine)

6) a=4 si b=2=>242+234+424=900 (nu convine)

7) a=1 si b=5=>215+531+154=900 (nu convine)

8) a=5 si b=1=>251+135+514=1100 (nu convine)

9) a=3 si b=3=>233+333+334=900 (nu convine)

ab apartine{(2;1); (1;2)}
