#"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"#
#x=3,y=7#
#y=k/xrArrk=x xxy=3xx7=21#
#"equation is " color(red)(bar(ul(|color(white)(2/2)color(black)(y=21/x)color(white)(2/2)|)))#
