Well. For starters, let's say X= the number of hours of the hardworking graphic artist (The one that worked the extra 3 hours). And Y= The number of hours the lazy graphic artist worked.

So that would mean that X+Y=27 (since x and y are both the hours that the graphic artists worked)

But you know what? If the lazy worker (Y) worked 3 hours to catch up with X, it's be the exact same thing...*clears throat* In other words Y%2B3=X (X is left alone since he already worked the extra 3 hours)

Now we substitute the Y+3 for X. Like this.
Y%2B%28Y%2B3%29=27
But if you simplify it, that's the exact same thing as 2Y%2B3=27
Now, you subtract the 3 from both sides %282Y%2B3%29-3=27-3, Making 2Y=24.
Then you divide both sides by 2, so you can simplify the equation to Y. So that would be 2Y%2F2=24%2F2. Therefore, your answer would be Y=12.
I hope I wasn't too confusing ^^' Best of Luck! :D
