Question #9bdca

Answer 1

`y=162n+13`

Explanation:

For formatting maths have a look at https://socratic.org/help/symbols

Better if you do not use star for multiply but use xx. Be careful if you wish to use xx for multiply next to an `x`. Odd things happen so you need to put a gap between them.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Multiply everything inside the bracket by 9

So `9(18xxn) ->9xx18n=162n`

Putting all of this together we have:

`y=7+162n+14-8`

Changing the order

`y=162n+14-8+7`

`y=162n+13`
