For example, The first equation contains variables 'a' and 'b', Second 'a' and 'c', Third 'a' and 'd', and so on. So If i want to get an equation with 'a' and b,c,d,... (That means 'a' on x-axis and b,c,d,e,... on y-axis). Is there any software which can solve this problem?

Sally has a box of donuts.
She gives 1/2 of the total to her mom and another 1/2.
She gives 1/2 of what's left to her aunt and another 1/2.
She gives 1/2 of what's left to her sister and another 1/2.
She has 1/4 of a dozen left over.

How many donuts did she start with and how many did each person get?

Please show me the algebra equation you used to get this answer.

Thank you so much

(BIG)/(JOKE) = 0.HAHAHAHAHA... (repeating)

BIG is a three digit number
JOKE is a four digit number
0.HAHAHA... is a repeating decimal with two repeating digits

Replace each letter using each of the numbers 1-9 only once such that the equation holds true.

I had solved this once before back in high school, but my solution was not very elegant. I cleverly eliminated a very large amount of the possibilities and began guess/checking on the remaining possibilities with a calculator. I am just curious if there is a more elegant solution.

Oh, and there are multiple solutions that will work (around 4 or 5 if I remember right).

Using the fact that h(x)=ln{x+SQRT(1+x^2) has derivative h'(x) =1/{SQRT(1+x^2)} solve the initial-value problem dy/dx=y/{SQRT(1+x^2) ,
(y greater than 0 ), y = 2 when x = 0, giving the solution in explicit form.

Right, I have taken the y accross to the LHS and then integrated both sides and I got y^2=2ln{x+SQRT(1+x^2) + C where C is a contstant. I think that is ok but I don't know what to do from there !!
