Question

If x = 2 and y = 4, find (x/y)x-y + (y/x)y-x ?

Answer 1

Answer:

Step-by-step explanation:x-y=a+b ax+by=a2 + b2

Answer 2

Answer:

PLACE THE VALUE OF x AND y IN EQUATION

$( \frac{x}{y} )x - y + ( \frac{y}{x})y - x \\ \\ ( \frac{2}{4} )2 - 4 + ( \frac{4}{2} )4 - 2 \\ \\ ( \frac{1}{2} )2 - 4 + (2)4 - 2 \\ \\ 1 - 4 + 8 - 2 \\ = 3$
