Answer 1

Answer:

2x=5y

Step-by-step explanation:

given;

        x=35

        y=14

         also;  x=cy

        so;   35=c (14)

               5=c(2)

                  c=5/2

substitute in the give equation;

                                               x=5/2y

                                                2x=5y is the answer

Answer 2

Answer:

2 x =5 y is the answer of your question
