The answer is

$n = 4.67$ $n = 4.67$

Explanation:

$13 n - 16 = 7 n + 12$ $13n - 16 = 7n +12$

$13 n = 7 n + 12 + 16$ $13n =7n +12 +16$

$13 n - 7 n = 12 + 16$ $13n - 7n = 12 + 16$

$6 n = 28$ $6n = 28$

$n = \frac{28}{6}$ $n = 28 / 6$

$n = \frac{14}{3}$ $n =14/3$

So

$n = 4 . ¯ 6$ $n = 4.bar(6)$

Round it up to,

$n = 4.67$ $n = 4.67$

$n = \frac{14}{3}$ $n=14/3$

Explanation:

$collect terms in n on the left side of the equation and$ $"collect terms in n on the left side of the equation and "$
$numeric values on the right side$ $"numeric values on the right side"$

$subtract 7 n from both sides$ $"subtract "7n" from both sides"$

$13n-7n-16=cancel(7n)cancel(-7n)+12$

$6n-16=12$

$"add 16 to both sides"$

$6n=28$

$"divide both sides by 6"$

$(cancel(6) n)/cancel(6)=28/6$

$n=28/6=14/3$
