`a,`
`(2x-3)/24 = (3x-1)/32`
`-> (2x-3) . 32 = (3x-1) . 24`
`-> 64x - 96=72x - 24`
`->64x - 72x = 96-24`
`-> -8x=72`
`->x=72 : (-8)`
`->x=-9`
Vậy `x=-9`

`b,`
`(13x-2)/(2x+5) = 76/17 (x \ne (-5)/2)`
`-> (13x - 2) . 17 = (2x+5) . 76`
`-> 221x - 34 = 152x + 380`
`-> 221x - 152x =34+380`
`-> 69x = 414`
`->x=414 : 69`
`->x=6` (Thỏa mãn)
Vậy `x=6`
