Question 143162
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. <br>
So that would mean that X+Y=27 (since x and y are both the hours that the graphic artists worked)<br>
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+3=X}}} (X is left alone since he already worked the extra 3 hours) <br>
Now we substitute the Y+3 for X. Like this.<Br> {{{Y+(Y+3)=27}}}<br> But if you simplify it, that's the exact same thing as {{{2Y+3=27}}} <br> Now, you subtract the 3 from both sides {{{(2Y+3)-3=27-3}}}, Making {{{2Y=24}}}. <Br> Then you divide both sides by 2, so you can simplify the equation to Y. So that would be {{{2Y/2=24/2}}}. Therefore, your answer would be {{{Y=12}}}.<br> I hope I wasn't too confusing ^^' Best of Luck! :D
