What is the value of x in the equation 3x – y = 18, when y = 27?

Hey!
Okay so we first can take out "y" and put in 27 since the question is stating that y=27.
Now we are going to Add 27 to both of the sides to make the problem look like this: 
3x-27+27=18+27
Got it?
Now we have step 2. 
Divide 3 by BOTH sides.

And you get 15, Therefore you have x=15

Iwould say this is false, because the mean and median are similar, though the mode is way different. but it might be true depending how you like at it. sorry if i'm being confusing : )
