Question 158499
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
