( 5x - 3y ) / ( 5y - 3x ) = 3/4
   Cross multiplying the numbers in the left and right ,
 4 (5x - 3y) = 3 (5y - 3x)
  Opening the brackets ,
  20x - 12y = 15y - 9x
  Grouping like terms to one side ,
 20x + 9x = 15y + 12y
  29x = 27y
→ 29 * x = 27 * y
→ x / y = 27 / 29
→ x:y = 27:29

5x-3y/5y-3x=3/4
cross multiply
we get
4(5x-3y)=3(5y-3x)
20x-12y=15y-9x
on transposing
20x+9x=15y+12y
29x=27y
Ratio
x:y=27:29
