Tìm x biết:

x - 2/5 = 1 - x/6

2 câu trả lời

`(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`
