Question

determina nr x astfel 6 supra x+2 ∈ N

Answer 1

x poate fi0, 1 si 4
6 supra 1+2 = 6÷3=2 ,€N
6 supra 4+2= 6÷6=1 €N 6 supra 0+2=6÷2=3

Answer 2

$\frac{6}{x+2}$
$x$∈${0,1,4}$
$x=0 =\ \textgreater \ \frac{6}{0+2} =3$∈$N$
$x=1=\ \textgreater \ \frac{6}{1+2} = \frac{6}{3} = 2$∈$N$
$x=4=\ \textgreater \ \frac{6}{4+2} = \frac{6}{6} =1$∈$N$
