x = y - (5/y), where x and y are both > 0. If the value of y is doubled in the equation above, the value of x will
Choices
A) decrease	B) stay the same	C) increase four fold	D) doubles	E) triples
Alternate approach   Plug in some values of y &gt; 0   Let y = 10   So, x = y - (5/y)   Or, x = 10 - (5/10)= 
<gadget id="calculator">10 - (5/10)</gadget>
<output>19/2 = around 9.5</output>
9.5   Let y= 20   So, x = y - (5/y)   Or, x = 20 - (5/20)= 
<gadget id="calculator">20 - (5/20)</gadget>
<output>79/4 = around 19.75</output>
19.75   So, x increases from 9.5 to 19.75   Hence the number increases 2 times, thus the correct answer will be (doubles)
