Question 212890: Hello. I do not know if this fits into the right category but I tried my best. Ok so I need help with solving for the variable. I have tried and got some of them but these two I can not seem to get. If you can show me step by step how to do these that would help a ton and thank you in advance. Ok so my question is:
y= u+1/u+2 solve for u
and the other one i did not get is:
ax+b=cx+d solve for x
if you could help me with those I would apreciate it so much!
Thanks for your time,
Kevin

Well I am glad you asked this because these problems a little challenging. The problem is I'm not sure how to explain how to do this...so i'm just going to take you step by step through the process.

First we multiply both sides by (u+2) and get

Now we subtract u from both sides.

Next we distribute the y.

Rearrainging a little we get:

now we factor out a u.

subtract 2y from both sides.

Now we divide both sides by y-1.

The next problem is somewhat similar to the problem above. First we subtract cx from both sides:

Next we rearrange a little

Subtract b from both sides

Factor out an x

And divide by a-c
