The answer to your question is 0.1
So when you work with variables (x, y or any other letter), when they're beside a number it usually means to multiply.
So 3y can also be written as 3(3). So 3 multiplied by 3 is equal to 9
So now our problem looks like this,
x/9.
Since we already know what x is equal to, our problem will look like this
18/9.
So now all we have to do is divide.
18 divided by 9 is 2
So therefore, your answer is 2.
I hope this helps :)
