Explanation:
#"the initial statement is "xprop1/y#
#"to convert to an equation multiply by k the constant"#
#"of variation"#
#rArrx=kxx1/y=k/y#
#"to find k use the given condition"#
#x=4" when "y=9#
#x=k/yrArrk=xy=4xx9=36#
#"equation is " color(red)(bar(ul(|color(white)(2/2)color(black)(x=36/y)color(white)(2/2)|)))#
#"when "y=6" then"#
#x=36/6=6#
