Question

plz help 1/2-3/4x+2.

Answer 1

There are no common terms. That means you must cross multiply.
2(4x + 3) 3(2)
-------- (-) -------
2 4x + 2

--------------------

Now factor: 8x + 6 and 6

8x + 6 6
------- (-) ------
2 4x + 2

Can you do the next step?

Answer 2

so then you cross out 8x and 4x?

Answer 3

and that becomes 2 on top and 1 on the bottom replacing where they were?

Answer 4

Look at: 8x + 6 ==> 4x + 2
Look at: 2 ==> 6

Do you see a divisible pattern?

Answer 5

yes.

Answer 6

Go ahead and give it a shot by cross dividing.

Answer 7

okay

Answer 8

32x+12/12?

Answer 9

Good attempt, but you it wrong. Remember when you're trying to simplify fractions you always divide the bottom by the top. When dividing it should always be cross division. Meaning I do the opposite of cross multiplying.

So let's take 8x + 6 and 4x + 2

8x + 6 6
------- (-) ------- < ==== Now solve the top right:
2 4x + 2

8x
-- = 2x
4x

6
-- = 3
2


Plugging it in:

2x + 3 6
------- (-) -------
2 1 <==== Out denominator canceled upon dividing.
I put the 1 in order to keep it in fraction form.

Now we solve for the denominator by:

6
-- = 3
2

This,

2x + 3 3
------- (-) ------
1 1

This becomes: 2x + 3 - 3,

Can you take it from here?

Answer 10

yah I think so, so then once it becomes that thenI cross out 3 and 3? which beomes just 2x?

Answer 11

Yes, 3 - 3 = 0

You're left with 2x

Answer 12

The last thing you do is subtract
Steps are:

> Look for factors:
> Multiply/distribute
> Cancel
>Subtract

Answer 13

okay one thing. my choices are x+2 and 2 which form shud it be in?

Answer 14

x + 2

Answer 15

thank you ver very much :)
