Any help would be appreciated!!! Thanks We require a sole x. With x terms together, they can be factorised there is now a sole x
Archie Mead solved for x. If your original function was y= f(x), and you want you still need to "swap" x and y. If , then, after arriving at , then . You could, also, first swap x and y and then solve for y. That will give exactly the same thing.
Another way to do it is: Then swap and , and solve for .
