    $x^{}$ + $\frac{19}{3}$ + $x^{}$ + $\frac{13}{5}$ = $x^{}$ + $\frac{7}{7}$ + $x^{}$ + $\frac{1}{9}$
    ⇔ $2x^{}$ + $\frac{19}{3}$ + $\frac{13}{5}$ = $2x^{}$ + $1^{}$ + $\frac{1}{9}$
    ⇔ $2x^{}$ – $2x^{}$ = $1^{}$ + $\frac{1}{9}$ – $\frac{19}{3}$ – $\frac{13}{5}$
    ⇒ $0^{}$ = $\frac{218}{45}$ $(Vô^{}$ $lý)^{}$
