Expression 1:
And because
Therefore you can write expression 1 as:
Try to do something similar for the other 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)
