[tex]\\ \sf\longmapsto \dfrac{1}{x}+\dfrac{1}{2x+3}=\dfrac{1}{3.5}[/tex]

[tex]\\ \sf\longmapsto \dfrac{2x+1+x}{2x^2+x}=\dfrac{1}{3.5}[/tex]

[tex]\\ \sf\longmapsto \dfrac{3x+1}{2x^2+x}=\dfrac{1}{3.5}[/tex]

[tex]\\ \sf\longmapsto 3.5(3x+1)=2x^2+x[/tex]

[tex]\\ \sf\longmapsto 11.5x+3.5=2x^2+x[/tex]

[tex]\\ \sf\longmapsto 2x^2-9.5x-3.5=0[/tex]
