$7 - 3 n$ $7 - 3n$

$3 (4 + n) - 5$ $3(4 + n) - 5$

First you remove the brackets, by multiplying all that is outside with the digits inside the bracket..

$3 \times 4 + 3 \times n - 5$ $3 xx 4 + 3 xx n - 5$

$12 + 3 n - 5$ $12 + 3n - 5$

$12 - 5 + 3 n$ $12 - 5 + 3n$

$7 - 3 n$ $7 - 3n$

How do you simplify the expression 3(4+n)−53(4+n) - 5?
