\[\frac{ -4+20x }{ 4 }\]
Simplify ?

Divide both -4 and 20x by 4

but 4 doesnt goin to -4

No, because 4*1=4 and not -4

-1

OK, so -4/4 = -1
Now you have to do: 20x/4

You lost x

5x

Done!

so thats my final answer are my final equation

You have -4 and 5x, so the final answer is... -4+5x

how bout this one
\[-\frac{ 1 }{ 2 }(4-6a)\]

Use the distributive property: a(b-c)=ab-ac

I dont knoe the distributie Prop

okay I see

What do you get?

how do I multiply a fraction in to a number

Just forget the "-" for a while.
1/2 * 4 means you have four halves. How many is that?

2 wholes

-2

Right!, now the other one...

so for the other half it be-3 the i would be left with(-2- -3) and my answer be -5

You have to multiply, so -1/2 * -6a = ...

6 isn't negative that was the subtraction sign

OK, so save it for later. So: -1/2 * 6a = ...

-3

You lost the a

-3a ugh srry:p

so then my equation would be(-2 - -3a)

the my answer should be -5a right

No, -2 hasn't got an a with it, so you can't add it to 3a

So it would be -2+3a

-- = +

so it be 1a right

No, it would be -2+3a.
This cannot be written shorter!
If it was -2a+3a this would be 1a or a.

oh okay got it
