Answer: Hence, there are 36 total number of invited guests.
Step-by-step explanation:
Let the total number of invited guests be 'x'
Part of those invited had already arrived =
Number of people just arrived = 6
According to question, it brings the number at the party to of those invited.
So, it becomes,
Hence, there are 36 total number of invited guests.

I'm assuming that you can solve these things. The top determinant comes to -180. The x value comes to - 540. When divided by the top one x = 3
The bottom determinant (y) comes to 900 and when divided by - 180 makes y = - 5. The checks out with actually solving the system of equations some other way.
