Question

If 5x = 7y =17; 7x=5y=19 then find x-y​

Answer 1

Answer:

x-y can be either 1 or -1

Step-by-step explanation:

5x+7x+7y+5y=19+17

12x+12y=36

so if X is 2 and y is 1

then,12(2)+12(1)=36

24+12=36

36=36

or if X is 1 and y is 2

then,12(1)+12(2)=36

12+24=36

24+12=36

therefore both ways it is correct
