Explanation:
#"the initial statement is " yprop1/x#
#"to convert to an equation, multiply by k, the constant"#
#"of variation"#
#rArry=kxx1/x=k/x#
#"to find k, use the given condition"#
#y=k/xrArrk=yx#
#"when x= 35 " y=1/5#
#rArrk=1/5xx35=7#
#"equation of variation is " color(red)(bar(ul(|color(white)(2/2)color(black)(y=7/x)color(white)(2/2)|)))#
