`(x + 2035)/11 + (x + 2036)/12 = (x + 2037)/13 + (x + 2038)/14`

`=> ((x + 2035)/11 - 1) + ((x + 2036)/12 - 1) = ((x + 2037)/13 - 1) + ((x + 2038)/14 - 1)`

`=> (x + 2024)/11 + (x + 2024)/12 = (x + 2024)/13 + (x + 2024)/14`

`=> (x + 2024)/11 + (x + 2024)/12 - (x + 2024)/13 - (x + 2024)/14 = 0`

`=> (x + 2024) . (1/11 + 1/12 - 1/13 - 1/14) = 0`

Vì `1/11 + 1/12 - 1/13 - 1/4 /ne 0`

`=> x + 2024 = 0`

`=> x = 0 - 2024`

`=> x = -2024`

Vậy `...`
