I need help with rational equations

Question

anonymous · Answer

me too:-)

anonymous · Answer

so you don't know how to do them,?

anonymous · Answer

Dunno, post one, let me see...

anonymous · Answer

1/x+1 - 2/x-1 = 3

anonymous · Answer

Yup,  I can do that, what's the problem u r having?

anonymous · Answer

i don't know how to do it

anonymous · Answer

Do u know lcd?

anonymous · Answer

lowest common denominator

anonymous · Answer

That a no?

anonymous · Answer

last chance, speak or forever...

anonymous · Answer

1/x+1 - 2/x-1 = 3 | * x <=> 1 + x - 2 - x = 3x <=> x-x -3x = 1 <=> 3x=-1 <=> x=-1/3

anonymous · Answer

thank you newm1, you are the best

anonymous · Answer

Oh, so now u know how to do them, good.

anonymous · Answer

anonymous · Answer

No?, I will give him one on your behalf...

phi · Answer

Did you mean
$$\frac{1}{x+1}-\frac{2}{x-1}= 3$$

anonymous · Answer

Gave the solution to the given equation. Good point phi. Its hard when someone don´t use brackets.

phi · Answer

Newm1, I know you did it right, but it sure looks strange to post an equation with a +1 and a -1 which obviously cancel.

So meg.. did you leave out the parenthesis Did you mean
1/(x+1) - 2/(x-1) =3

anonymous · Answer

Answer's still right....

phi · Answer

True, but there is another answer x=0.  And the real point is to understand how to solve these. Are you going to take her test?

anonymous · Answer

She claimed she now understood them...

anonymous · Answer

The fact she clearly doesn't is entirely besides the point.
