Now we will compare the two equations we found in Hint # 1. We can rewrite the equations to look a little better and hopefully you will see the second terms are very similar. Let's try to cancel them out by multiplying the second equation by -2 and solve for (x+y). We then plug in our result into to first equation to solve for (xy). We now have found values for (x+y) and (xy). Can you find the value for (a+b)? If you need another hint, press the Hint #3 button below.
