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)
