1. Start with the original equation:
\ln(4x+5) = 0
2. Use the property of logarithms that \ln(y) = 0 \implies y = 1:
4x + 5 = 1
3. Subtract 5 from both sides to isolate terms with x:
4x = 1 - 5
4. Simplify the right side:
4x = -4
5. Divide both sides by 4 to solve for x:
x = \frac{-4}{4} = -1
The solution is:
x = -1
