Question

Please help me with this and i will reward 50 points if you answer all the areas.

Answer 1

C=total goals b=score started with 12 (idk, just say that you want to continue a game you’ve never finished before), ax=1 points per goal, and let's say c=winning score has to be greater than 50. x+12>50. SO for this, you could write that some people were playing a soccer match continuation. It was 9-0 in their last game, but they never finished, so they decided that they will continue from 9-0. Each score otherwise is 2 points. to win, you must get a greater score than 45 
I hope this helps :3
