$\frac{1}{2x}$ - 2021+$\frac{1}{3x}$ + 2022= $\frac{1}{15x}$ - 2023 - $\frac{1}{10x}$ - 2024
⇔ $\frac{1}{2x}$ + $\frac{1}{3x}$ - $\frac{1}{15x}$ + $\frac{1}{10x}$ = 2021 - 2022 - 2023 - 2024
⇔ $\frac{13}{15}$x = -4048
⇔ x = -4048 : $\frac{13}{15}$
⇔ x = $\frac{-60720}{13}$
Vậy: S={$\frac{-60720}{13}$}
