1. ## Simple: Solve for 'X'

i have found an answer to this but i would like to know if i am right. what do ye get?

Code:
X+1             2X+1            X + 2
___      =      ____       +   _____
2              10               3

Multiply every term by the LCD which is 30.

$30\left(\frac{x+1}{2}\right)=30\left(\frac{2x+1}{1 0}\right)+30\left(\frac{x+2}{3}\right)$

$15x+15=6x+3+10x+20$

Combine terms and solve......can you finish it?

3. what i have originally is 25, is that right?

4. Multiply every term by the LCD which is 30.

$30\left(\frac{x+1}{2}\right)=30\left(\frac{2x+1}{1 0}\right)+30\left(\frac{x+2}{3}\right)$

$15x+15=6x+3+10x+20$

$15x+15=16x+23$

$-x=8$

$\boxed{x=-8}$

5. cheers mate, i had the right idea but I was doing it wrong somehow. nice one
