`x-3/5 . x-7/3=-5/6`
`<=> x-3/5 . x=-5/6+7/3`
`<=> x-3/5 . x=-5/6+14/6`
`<=> x-3/5 . x=9/6`
`<=> x-3/5 . x=3/2`
`<=> x . (1-3/5)=3/2`
`<=> x . (5/5-3/5)=3/2`
`<=> x . 2/5=3/2`
`<=> x=3/2:2/5`
`<=> x=3/2 . 5/2`
`<=> x=15/4`
Vậy `x=15/4`
`x - 3/5. x - 7/3 = -5/6`
`=> ( 1 - 3/5 ). x = -5/6 + 7/3`
`=> 2/5. x = 3/2`
`=> x = 3/2 : 2/5`
`=> x = 15/4`
$Vậy$ `x = 15/4`
