Answer:

x = 324

Step-by-step explanation:

y=Kx

  • make k the subject of formula

=> Kx = y

=> k = y/x

  • add the value of y = 18 when x = 2.

=> k = 18/2

  • divide 18 by 2

=> k = 9

What is the value of x when y = 36?

=> x = Kx

  • substitute k equals to 9 and from the question y equals to 36 into this equation

=> x = 9(36)

  • multiply 36 by 9

=> x = 324
