-----------------
7 = n

Answer:

The required number is 7.

Step-by-step explanation:

It is required to find,

A number say 'x', such that, 27 is 6 more than 3 times the number.

That is, we have the relation, [tex]3x+6=27[/tex].

On solving, we get,

[tex]3x+6=27[/tex]

i.e. [tex]3x=27-6[/tex]

i.e. [tex]3x=21[/tex]

i.e. x = 7

So, the required number which hold the relation that '27 is 6 more than 3 times the number' is 7.
