Answer 2

Solving the Equation

To solve the equation 5x + 13 = 3(x + 9), we can follow these steps:

1. Distribute the 3 on the right side of the equation: - 5x + 13 = 3x + 27

2. Isolate the variable x: - Subtract 3x from both sides: - 5x - 3x + 13 = 27 - 2x + 13 = 27 - Subtract 13 from both sides: - 2x = 27 - 13 - 2x = 14

3. Solve for x: - Divide both sides by 2: - x = 14 / 2 - x = 7

So, the solution to the equation 5x + 13 = 3(x + 9) is x = 7.

Conclusion

The solution to the equation is x = 7. If you have any further questions or need additional assistance, feel free to ask!
