The sum of 5 times a number and -2, added to nine times a number.
.
Looking at the first part:
The sum of '5 times a number' and '-2'
we get
5x + (-2)

or
5x - 2
.
The above is then "added to nine times a number" to get:
5x - 2 + 9x
Combining x's we get:
14x - 2

Take it piece by piece: 
5 times a number, rewrite as 5x 
plus -2, nothing to rewrite there, that's already simplified, 

added to nine times a number, rewrite as 9x. 
Now, rewrite as an equation: 
5x-2+9x = (See, it already looks better!) 
Now combine like terms: 
5x + 9x -2= 14x - 2
