$y = 162 n + 13$

#### 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 $9 \left(18 \times n\right) \to 9 \times 18 n = 162 n$

Putting all of this together we have:

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

Changing the order

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

$y = 162 n + 13$
