Explanation:

\mathsf{\frac{1}{x+1}+\frac{2}{x+2}=\frac{5}{x+4}}

\mathsf{==> \frac{(x+2)+(2x+2)}{(x+1)(x+2)}=\frac{5}{x+4}}

\mathsf{==>\frac{3x+4}{x^2+3x+2}=\frac{5}{x+4}}

\mathsf{==>(3x+4)(x+4)=5(x^2+3x+2)}}

\mathsf{==>3x^2 + 16x+16=5x^2+15x+10}

\mathsf{==> 3x^2 + 16x +6=5x^2+15x}

\mathsf{==> 5x^2+15x-3x^2-16x-6=0}

\mathsf{==>2x^2-x-6=0}

\mathsf{==> 2x^2 - 4x + 3x - 6=0}

\mathsf{==>2x(x-2)+3(x-2)=0}

\mathsf{(x-2)(2x+3)=0}

\mathsf{x = 2 \:OR\:x=\frac{-3}{2}}

Please ask the next question again separately, I will answer it there.

Answer: x = 2 OR x = -3/2

I hope this helps. :D
