Answer: x = -3

Step-by-step explanation:

1. 2x + 3 + 7x = -24 (combine like terms, 2x + 7x)

2. 9x + 3 = -24 (subtract 3 from both sides of the equation, inverse operations)

3. 9x = -27 (divide -27 by 9 from both sides, inverse operations)

4. X = -3 (-27 divided by 9 is equal to -3, a positive divided by a negative is a negative)
