I understand that just a little. Well anyway i also know 8

While true it&#039;s fairly irrelevant in this context - but it&#039;s none the less correct.

2. ## Re:Help with Algebra??

Why don&#039;t you give me an algebra problem so you could tell me how much you could help me with?? Let&#039;s start off from the beginning then to advance. Please reply back.

3. ## Re:Help with Algebra??

The simple one:
2x + 3 = 2

1 1
--- + --- = 3
2x 5x

4. ## Re:Help with Algebra??

Tell me if i&#039;m correct.

The simple one:

x= - 1
----
2

x= 3
---
7

Is that right?? Please reply back. If you want to know how i got the answer i will show you my steps. Thanks.

5. ## Re:Help with Algebra??

Okay here goes
1)

2x = -1

-1
x= ---
2

So that one is correct.

2)

5x 2x
------ + ------ = 3
10x² 10x²

7x
----- = 2
10x²

20x² = 7x

20x = 7

7
x = -----
20

So that one isn&#039;t correct.

Let&#039;s try again

1 4
----- + ------ = 10
(x-1) 2x

Now remember these are off the top of my head so as much as I would like it they don&#039;t always end out with a nice even result, but hey... it&#039;s it jerryrigged math.

Give me all your steps for that one btw.

6. ## Re:Help with Algebra??

I did it another way and i got a different answer.

1 4
---- + ------------
(x-1) 2x

ok here we go. First we want to get rid of those fractions. We multiply each side by x-1. That leaves us with 1+40x-4. Once again we have to get rid of that other fraction. We multiply each side by 2x so 2x could cancel. That leaves us with 2x+40x-4.

7. ## Re:Help with Algebra??

okay:

1 4
----- + ------ = 10
(x-1) 2x

first we multiply both fractions by 1 - we do this by 2x/2x for first one and (x-1)/(x-1) for the other, since multipling any number by 1 does not alter it&#039;s value we are allowed to do this.
We pick these specific numbers from the divisor ( the lower part of the fraction) as you can see we do this &quot;crossed over&quot;

1 * 2x 4*(x-1)
-------- + ----------- = 10
(x -1)*2x 2x*(x-1)

Now we do the math - nothing changes but appearences

2x 4x - 1
--------- + ----------- = 10
2x² - 2x 2x² - 2x

Now we see that we can make these to fractions into a common fraction since they have the same divisor. This is also perfectly allowable since it does not alter the value of equation.

2x + 4x - 1
-------------- = 10
2x² - 2x

------------ this is the end of the part you have problems with understanding if I&#039;m correct ---

Now we multiply by 2x² -2x on both sides of the equation

2x + 4x -1 = 20x² - 2x

substract 2x from each side

4x -1 = 20x²

divide by x

4 - 1/x = 20x

We can now realise that this has no finite solution within the given scope - thus we can only express x as a function of x.

thus
1 1
x = --- + -----
5 20x

So this was a tricky one.
---

Let&#039;s try the same on a different equation

1 2
---- + ---- = 2
2x 4x

Now this one has a &quot;shortcut&quot; builtin - so bonus point for that one if you spot it, but try mindless to follow the method I showed you anyways, because the method is never wrong.

One way to check if you are correct in your calculations is to insert the value for x you found in the equation you were given - if it matches up you have found a usable solution.

First can you show me how to use my keyboard to raise a power of an expoent?? If not then i&#039;m going to use ^ and then the number i want as a power. Please reply back. Thanks.

9. ## Re:Help with Algebra??

^2 will give you ² if typed in one go, no spaces etc.
