$\longrightarrow{\green{ \: n = 30 }}$

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}$

$\frac{n}{3} - 5 = 5$

➼ $\: \frac{n}{3} = 5 + 5$

➼ $\: \frac{n}{3} = 10$

➼ $\: n = 10 \times 3$

➼ $\: n = 30$

Therefore, the value of n is 30.

$\large\mathfrak{{\pmb{\underline{\blue{To\:verify}}{\blue{:}}}}}$

$\frac{30}{3} - 5 = 5$

✒ $\: 10 - 5 = 5$

✒ $\: 5 = 5$

✒ $\: L.H.S.=R. H. S$

Hence verified.
