hi gAr
could you explain how you got the second line in your solution.i don't get it.
hi ganesh
hi ganesh
hi ganesh
have you tried to do any other problems?
correct.one tip though,when you get a solution you can always check by pluging the results into the equations.
oh yes i read that somewhere.i live in serbia
yeah preety sure is
where are you from?
i'm 14
we're almost the same age.
that's right.you're welcome.just watch out to spot your mistakes,but don't worry if you make one,everybody does.
i've wanted to ask you,how old are you?
do you understand why it is 0 instead of y?
hi zee-f
no actually you would get 0=-1x-2.Grom there you can get x.
hi zee-f
problem 17 is incorrect
again,2x-4 is not -2.you didn't make x dissapear.
What you can do is subtract the two equations.
it should be easier that way.
i got it from a mathematical magazine.
hi ganesh
hi bobbym
also missed your post on the small o,big O.
i'm sure that it's a small o
yeah you're right.i just put 10 instead of 20 by mistake.
ah,okay.
