(2/x)+(3/x+4)

That is beautiful presentation GoldenLeaf but there is no equal sign in the question.

Also since x is a denominator you probably should state right from the beginning that x≠0

$$\frac{2}{x}+\left(\frac{3}{x}+4\right)\\\\ =\frac{2}{x}+\frac{3}{x}+4\\\\ =\frac{5}{x}+4\\\\$$

$$\left({\frac{{\mathtt{2}}}{{\mathtt{x}}}}\right){\mathtt{\,\small\textbf+\,}}\left({\frac{{\mathtt{3}}}{{\mathtt{x}}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{4}}\right) = {\mathtt{0}}$$

$$\left({\mathtt{2}}\right){\mathtt{\,\small\textbf+\,}}\left({\mathtt{3}}{\mathtt{\,\small\textbf+\,}}{\mathtt{4}}{\mathtt{\,\times\,}}{\mathtt{x}}\right) = {\mathtt{0}}$$

$${\mathtt{2}}{\mathtt{\,\small\textbf+\,}}{\mathtt{3}}{\mathtt{\,\small\textbf+\,}}{\mathtt{4}}{\mathtt{\,\times\,}}{\mathtt{x}} = {\mathtt{0}}$$

$${\mathtt{4}}{\mathtt{\,\times\,}}{\mathtt{x}}{\mathtt{\,\small\textbf+\,}}{\mathtt{5}} = {\mathtt{0}}$$

$${\mathtt{4}}{\mathtt{\,\times\,}}{\mathtt{x}} = -{\mathtt{5}}$$

$${\mathtt{x}} = {\mathtt{\,-\,}}{\frac{{\mathtt{5}}}{{\mathtt{4}}}}$$
