2 Answers

The answer is

#n = 4.67#

Explanation:

#13n - 16 = 7n +12#

#13n =7n +12 +16#

#13n - 7n = 12 + 16#

#6n = 28#

#n = 28 / 6#

#n =14/3#

So

#n = 4.bar(6)#

Round it up to,

#n = 4.67#

#n=14/3#

Explanation:

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

#"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#
