Explanation:
#"assuming the variables are in "color(blue)"direct variation"#
#"that is "y=kxlarr" k is constant of variation"#
#"to find k use the given condition"#
#"when "x=12,y=8#
#y=kxrArrk=y/x=8/12=2/3#
#"equation is " color(red)(bar(ul(|color(white)(2/2)color(black)(y=2/3x)color(white)(2/2)|)))#
#"when "y=12#
#rArrx=(3y)/2=(3xx12)/3=18#
