**Algebra**

What did i do wrong? I am confused to the fact that -3 is the answer and not -3/26?
*July 7, 2009*

**Algebra**

That got all messed up. 4 is on top of the 3-x, 1 is over x+9, and 5 is over 3-x respectively So is the answer still -3 or -3/26? Thank you!
*July 7, 2009*

**Algebra**

It is typed as follows: 4 1 5 --- + --- = --- 3-x x+9 3-x So is the answer -3/26 or just -3?
*July 7, 2009*

Is it -3 or -3/26? I ran this problem through 2 calculators online and they both came up with -3/26? Can you explain why its only -3? Thanks
