Hi there!

So let's start by establishing what "x" and "y" are going to be in our equation:

x = the number of guests

y = the $8,000 budget

Here's the equation:

8,000 = 25.50x + 350

Now to solve the equation you just have to isolate the "x" :

8,000 = 25.50x + 350

Subtract 350 from each side of the equation

7,650 = 25.50x

Divide each side of the equation by 25.50

300 = x

So your answer is : 300 guests can attend the wedding so that Walt and Traci stay on budget!

Here you go! I really hope this helped, if there's anything just let me know! :)
