   5x^2 +5= 3x     5x + (5/x) = 3    x + (1/x) = (3/5)
$$\:\:\:\mathrm{5}\boldsymbol{\mathrm{x}}^{\mathrm{2}} +\mathrm{5}=\:\mathrm{3}\boldsymbol{\mathrm{x}} \\ $$$$\:\:\:\mathrm{5}\boldsymbol{\mathrm{x}}\:+\:\frac{\mathrm{5}}{\boldsymbol{\mathrm{x}}}\:=\:\mathrm{3} \\ $$$$\:\:\boldsymbol{\mathrm{x}}\:+\:\frac{\mathrm{1}}{\boldsymbol{\mathrm{x}}}\:=\:\frac{\mathrm{3}}{\mathrm{5}} \\ $$
