Answer 1

To find the difference, subtract -2x - 6 from x + 3. The answer is 3x + 9.

Step-by-step explanation:

To find the difference when -2x - 6 is subtracted from x + 3, we subtract -2x - 6 from x + 3.

x + 3 - (-2x - 6)

x + 3 + 2x + 6

Combine like terms: 3 + 6 = 9, x + 2x = 3x

This gives us the final answer: 3x + 9.
