Maths+ account~!

Just finish my acount and maths test today..
actually it is quite hard for me.. cuz i didnt really study it..
for maths, I just study simultaneous eq.. cuz this is the part that I dun understand..
but then.. simultaneous eq din come out~~!
argh..
I tot i know how to do the first few questions( cuz teacher told us that she arrange the question from easy to hard).. I know how to do.. but i forgot the formulae.. =.="
Hope that the formulae that i simply put inside is the correct formula lar ><

surprisingly, I know how to do the last question!
The last question is about linear programming.. graph.. find the missing eq..
So, I also cant estimate my maths result..
