Answer:
Second Option: = 2(y-2x)/(3y-5x)
Explanation:
The expression is:
=(2/x-4/y)/((-5)/y+3/x)
Taking LCM in both, numerator and denominator
= ((2y-4x)/xy)/((-5x+3y)/xy)
Since we know,
(a/b)/(c/d)=ad/bc
Applying the rule to the given fraction:
=(2y-4x)(xy)/(-5x+3y)(xy)
xy will be cancelled and we will be left with:
=(2y-4x)/(-5x+3y)
Taking 2 as common:
= 2(y-2x)/(3y-5x)
So the second option is the correct answer. ..
