Answer
$$ x = -3 $$
Explanation
$$ \begin{aligned} \frac{x+3}{x+4} &= 0&& \text{multiply ALL terms by } \color{blue}{ x+4 }. \\[1 em](x+4)\frac{x+3}{x+4} &= (x+4)\cdot0&& \text{cancel out the denominators} \\[1 em]x+3 &= 0&& \text{ move the constants to the right } \\[1 em]x &= -3&& \\[1 em]x &= -3&& \\[1 em] \end{aligned} $$
