Answer: 10x + 19
Step-by-step explanation:
Because we don't know what x equals, and theres no indication of what this expression equals, the most we can do is simplify.
First, use distributive property:
4x + 28 + 6x - 9
Next, add like terms: 4x and 6x are like terms, 28 and -9 are also like terms.
4x + 6x = 10x
28 + -9 = 19
10x + 19 is the simplest form we can go.
