Need help simplifying some expressions!
Ok, I have a couple of expressions that I need to put in terms of X (and only X), where X=(A-B)/A. I have listed them below...I know that this should be relatively simple but I seem to be having alot of trouble with this. Could anyone please show/explain how to go about simplifying these expressions? Thanks a bunch in advance!
Expression 1: (B)/((3*A)-(2*B))
Expression 2: (2*(A-B))/((3*A)-(2*B))
Expression 3: (A-B)/((3*A)-(2*B))
Expression 4: ((-.5*A)-B)/((.5*A)-B)
Re: Need help simplifying some expressions!
Expression 1: 
And because 
Therefore you can write expression 1 as:
![\frac{A-Ax}{\frac{3B}{1-x}-2A+2Ax}=\frac{A-Ax}{\frac{3A-3Ax}{1-x}-2A+2Ax}=\frac{A(1-x)}{A\left[\left(\frac{3-3x}{1-x}\right)-2+2x\right]}=...](http://latex.codecogs.com/png.latex?\frac{A-Ax}{\frac{3B}{1-x}-2A+2Ax}=\frac{A-Ax}{\frac{3A-3Ax}{1-x}-2A+2Ax}=\frac{A(1-x)}{A\left[\left(\frac{3-3x}{1-x}\right)-2+2x\right]}=...)
Try to do something similar for the other expressions.
