`(x - 2)/5 = (1 - x)/6`
`=> 6(x - 2) = 5(1 - x)`
`=> 6x - 12 = 5 - 5x`
`=> 6x + 5x = 5 + 12`
`=> 11x = 17`
`=> x = 17/11`
Vậy `x = 17/11`
`(x-2)/5 = (1-x)/6`
`=> 6.(x-2) = 5.(1-x)`
`=> 6x-6.2 = 5.1 - 5x`
`=> 6x - 12 = 5 - 5x`
`=> 6x + 5x - 12 = 5`
`=> (6+5)x = 5 + 12`
`=> 11x = 17`
`=> x = 17 : 11`
`=> x = 17/11`
Vậy `x = 17/11`
