Well in this case, to see which is greater, let's just say that: x=4 <--- 4 is less than 5 y=5
Now substitute: 2x-y 2y-x 2(4)-5 2(5)-4 8-5 10-4 3 6
Which of these is greater, 3 or 6? 6, obviously. Therefore, we know that 2y-x is greater. <em> </em> <em>Don't forget to rate this answer the Brainliest!</em>
