Answer:
x+3
Step-by-step explanation:
If you factor 5 out of the denominator of the first expression, 5x+15 turns into 5(x+3).

Ive attached an image that shows an example of simplifying an expression using a the same technique.
On this one you should multiply the percentby a 100, that should give you the sales tax
(0.99x) + 18 = 1.19x
18 = 1.19x
- 0.99x
18 = 0.2x
18/0.2 = x
90 = x
