Can someone please help me solve (1/x) + (1/(x+3))

I don't even think this is meant to be a hard question, but I can't figure out how to solve it.....

OK, that can be done! :)

This is just like adding two fractions and expressing in simplest form (reduced form).

The LCD here is x(x+3) so multiply the first term by (x+3)/(x+3) and the second term by x/x.

That will give you:

(x+3)/x(x+3) + x/x(x+3)

Now they have the same denominator so you can add the numerators to get

(2x + 3) / x(x+3)

And that is the final answer, in simplest form.

:)

(1/x) + (1/(x+3))
equate the denominator,
= (1/x)((x+3)/(x+3)) + (1/(x+3))(x/x)
= (x+3)/(x(x+3)) + x/(x(x+3))
= ((x+3)+x)/(x(x+3))
= (2x+3)/(x(x+3))

You need to cross multiply the denominators with the numeraters, then you can isolate x, and find it.
