Step-by-step explanation:

\sf \large{ \green{ \underline {\underline{ \sf \: GIVEN \:  \:   \: QUESTION :-}}}}

 \sf \: (5x - 7y)  : (2x - 6y) :   \: : 2 :3

\sf \large{ \green{ \underline {\underline{ \sf \: TO \:  \:  FIND :-}}}}

 \sf \: value \: of \: x : y

\sf \large{ \green{ \underline {\underline{ \sf  SOLUTION:-}}}}

We know that if there are no.s a,b,c,d are in proportion

a:b::c:d

then

 \sf \: a \times d = b \times c

 \sf \: (5x - 7y) \times 3 = (2x - 6y) \times 2

 \sf \implies15x - 21y = 4x - 12y

 \sf \implies15x - 4x=  - 12y + 21y

 \sf \implies11x=  9y

 \sf \implies \frac{x}{y} =  \frac{9}{11}  \\

 \sf \: x : y = 9  : 11

Thank you..
