Final answer:
After simplifying the equation 8x + 9 - 4x = 25, we found that the correct solution is x = 4, not x = 6, as the initial answer provided did not satisfy the equation.
Step-by-step explanation:
To check the solution of the equation 8x + 9 - 4x = 25, we need to simplify it and see if the solution provided.
Here's the simplification process:
- First, combine like terms on the left side of the equation: 8x - 4x + 9 = 25.
- This simplifies to 4x + 9 = 25.
- Subtract 9 from both sides to isolate the term with x: 4x = 16.
- Finally, divide by 4 to solve for x: x = 4.
Therefore, the correct solution is x = 4.
