Question

Check solution of 8x+9-4x=25.

Answer 1

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:

1. First, combine like terms on the left side of the equation: 8x - 4x + 9 = 25.
2. This simplifies to 4x + 9 = 25.
3. Subtract 9 from both sides to isolate the term with x: 4x = 16.
4. Finally, divide by 4 to solve for x: x = 4.

Therefore, the correct solution is x = 4.
