Answer 1

[tex]\it \dfrac{7}{3} \ \textless \ n\ \textless \ \dfrac{10}{3} \\\;\\ \\\;\\ \dfrac{7}{3} \ \textless \ \dfrac{9}{3} \ \textless \ \dfrac{10}{3} \Longrightarrow \dfrac{7}{3} \ \textless \ 3 \ \textless \ \dfrac{10}{3} \Longrightarrow n = 3. [/tex]

$\it x,x+2=7,5 \Longrightarrow x,x = 7,5-2 \Longrightarrow x,x = 5,5$
