Question

Rezolvati ecuatia:
3(×+1)=3(×+2)-3

Answer 1

[tex]3(x+1)=3(x+2)-3 \\ 3x+3=3x+6-3 \\ 3x+3=3x+3=>x~poate~avea~orice~valoare \\ x=\{0,1,2,3,......\}[/tex]

Answer 2

3x+3=3x+6-3
3x-3x=6-3-3
0=0
=>x∈{0,1,2,3,4,5.........................................,100,101.................................}
