#n=-5#

Explanation:

Distribute the bracket, collect terms in n on the left side of the equation and numeric values on the right side.

#rArr-n-56n-21=264#

collect like terms on the left side.

#rArr-57n-21=264#

add 21 to both sides.

#-57ncancel(-21)cancel(+21)=264+21#

#rArr-57n=285#

To solve for n, divide both sides by - 57

#(cancel(-57) n)/cancel(-57)=285/(-57)#

#rArrn=-5" is the solution"#
