This needs to be simplified. I need the work and answer.

THANKS A TON!!

Hi SlowlyFading;

If you saw the problem I worked through in the previous post then you should have some idea how to do this. In fact this one is easier than that one.

What is on the top that is the exact same as what is on the bottom? Then you can cross them out. Give it a try.

SlowlyFading · 2012-09-07 03:38:12

I have a very slight idea of how to do these.. Barely. I'm very bad with these type of problems.
Could I have the work for this problem?

bobbym · 2012-09-07 06:12:39

Do you see the (2x-3) expression? They even have bracketed it for you. Let's start right there.

SlowlyFading · 2012-09-08 07:05:44

I need to simplify it? By adding those terms together?

bobbym · 2012-09-08 07:08:36

Hi SlowlyFading;

One step at a time. Take and cross out on the top and bottom every occurrence (2x-3). What do you get? Please give it a try.

SlowlyFading · 2012-09-11 04:14:11

I don't know how to do that..

bobbym · 2012-09-11 06:20:07

Hi;

Write the problem on a piece of paper and cross out each (2x-3) as I have done below.

Now just take what is left after you replace each crossed out (2x-3) with a 1

SlowlyFading · 2012-09-12 06:05:55

So,

It would become

?

bobbym · 2012-09-12 06:09:49

Hi SlowlyFading;

If you replace the first (2x-3) that is crossed out by a 1 you would get.

You try the next one.

SlowlyFading · 2012-09-13 05:03:42

So,

Except the "3" should be the first number in the equation.

SlowlyFading · 2012-09-13 05:04:43

I really don't know how to do this as you can see.

bobbym · 2012-09-13 07:12:52

That is okay, I will show you how.

You replace the

with a one. I have done the next part

you try the last part.

SlowlyFading · 2012-09-18 06:07:09

So,

I don't know how to insert that dot you have in your posts so I just slept out "dot" instead

bobbym · 2012-09-18 06:09:38

Hi;

Yes, that is correct! Can you simplify a little bit more?

SlowlyFading · 2012-09-27 05:22:10

?

SlowlyFading · 2012-09-27 05:24:19

That second "dot" wasn't meant to be there, my bad.

bobbym · 2012-09-27 07:02:13

Hi;

That is not quite correct.

Let's look at this again. 3 * 1 = 3. What does x * 1 equal?

SlowlyFading · 2012-09-29 04:10:30

becomes

bobbym · 2012-09-29 04:15:43

Hi;

That is correct, now there is one more bit of simplification.

SlowlyFading · 2012-09-29 05:39:39

?

bobbym · 2012-09-29 05:46:51

Hi;

Not quite. You have ( 3 - x ) over one. What does anything over one equal?

SlowlyFading · 2012-10-02 00:42:55

?

bobbym · 2012-10-02 04:00:30

Hi;

Not quite. You have ( 3 - x ) over one. Where did the x go?

If

Then what does

equal?
