Question 341003
I am going to guess you are supposed to solve for x, the steps are below.

{{{x/(3sqrt(6))=(3sqrt(6))/9}}}  <--- Original equation
{{{x=((3sqrt(6))^2)/9}}}  <--- Isolate x by multiplying both sides by {{{3sqrt(6)}}}
{{{3sqrt(6)*(3sqrt(6))=9*6=54}}}  <--- Solve the numerator
{{{54/9=x}}}  <---Numerator divided by denominator 
{{{highlight(x=6)}}}  <--- Final answer
