Y*x^2=k
y=3, x=18 ⇒ 3*18^2=3*324=972=k
x=3, 972=y*x^2=y*9
y=972/9
y=108

Step-by-step explanation:

Using the properties of logarithms, the left side of the equation becomes

$\log{3x^3} - \log{x^2} = \log{3x}$

while the right hand side becomes

$\log{27} - \log{x} = \log{\frac{27}{x}}$

so we end up with

$3x^2 =27 \Rightarrow x = 3$
