Answer:

y= ? / ? x

==> y = 12/3 x

y = 4x

Explanation:


x \: and \: y \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ let \: the \: relation \: be \: k\\ x = ky \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ - ky = - x \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ ky = x \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ k = (x)/(y) \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ k = (12)/(3) \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ k = 4

K = 4
