Homework help!
Additional mathematics...
Simutaneous equations:
x-y+1/12=0,
1/x-1/y-2=0
Solve.
Second question,
Solve x^2=5+2/x, giving solutions to 2 decimal places where necessary.
Please help... I'm desperate. Thank you.
I want to know the working...

Why don't you Google some maths forums?
You surely can't do any worse than posting an algebra problem in a Flash development forum.

No!
with simultaneous equations, solve for x in the first equation, plug it into the second equation, solve for y, plug into previous solution for x and check your answer.
With quadratic equation either use the quadratic formula or complete the square to solve for x.
if you can't understand me, then look it up in your algebra book.

for the first question, i came to -14=0... how come!?

Hi,
Post your problem on MathsNet forum and for sure you'll have your answer soon

No!
I don't know what you're doing, you should really be doing this on your own if you want to learn it.
I'll give one last hint, though
x = y-1/12
y = x/(1-2x)
Now, don't forget to show our work and how you got to what I just posted.

calpomatt, your working is wrong... you forgot to times x for -2
nevermind...
thanks for ur efforts anyway. i appreciate it

additional mathematic? in igcse? it will get harder
x-y+1/12=0,
1/x-1/y-2=0
x=y-1/12
1/(y-1/12)-1/y-2=0
1-(y-1/12)/y-2(y-1/12)=0
y-(y-1/12)-2y(y-1/12)=0
1/12-2y^2-2y/12=0
1-24y^2-2y=0
24y^2+2y-1=0
now use the quadratic formula to solve it. same with the next one

Domo Arigato!
(Quadratic Formula)
I really enjoy forgetting. When I first come to a place, I notice all the little details. I notice the way the sky looks. The color of white paper. The way people walk. Doorknobs. Everything. Then I get used to the place and I don't notice those things anymore. So only by forgetting can I see the place again as it really is.
