It may look intimidating, But it's only distribution! My Algebra 1 teacher called this the RAINBOW of Algebra, because when we distributed the numbers, we drew arrows and made it look. Well like a rainbow! Let me explain it the best I can.
First of all. Take care of all of the negatives and apply them into what is inside of the parenthesis. Since the problem is 4-(3x+2)=1-(5-7h) , By looking at the outside of the parenthesis, we see that both of them have a - symbol in front of them. We would then change the first half of the equation to 4(-3x+-2) and the second half to 1(-5+7h). If you didn't know already, two negatives make a positive. Hints why things that were already negative turned positive. Now that we've distributed the -, we can move onto the 4.
This is where multiplication skills come in handy!
(This is where we begin to rainbow. See attached.)
Take the four, and multiply it to everything inside the parenthesis. You should end up with (-12x-8)
Now the other side, taking the one and distributing it to the (-5+7h). You should get (-5+7h)
Now you have what looks like -12x-8=-5+7h
If you need to know how to do the rest, repost the question in the simple form. Hope I helped. Good luck.

Since you just posted this I will assume that you are not too far away
please answer these for me, I want to know what you can do.

1) 4(3x-6)
2) -2(x-5)
and
3) 5-3(2x-4)
4) -(x+6)

Ok so i forget how to do these problems,so can you show me by just doing this 1 problem plz! My science exam is tomorrow and im scared that im going to fail,plus on top of that i have a social studies exam on Wednesday:
[size=150]Lactose is a sugar that is found in milk. What is the percent by mass of a solution made by dissolving 71g of lactose in 729g of water? [/size]

Okay Ariel,
The fraction of lactose will be weight of lactose divided by the Total weight of the solution
If you want to change that fraction to a percentage you multiply by 100 and put a percent sign.

Now I am going to really annoy you by asking,
What is the answer?

[quote="TheApeFornicator"] Depends on whether you are losing or gaining because of tax -

You would either multiply your base by 1.09 or by .91.

Hey Greasy,
Surely this one deserves some feedback. I was really proud of myself finding this for you!

Thanks special,
They are cool (and beautiful) pictures, I didn't know that snow crystals were so varied. (although those ones all seem to be more or less hexagonal - is that always the case?)
I suppose I should have known. I seem to recall hearing that no 2 snow flakes are the same, they are as unique as finger prints. Does that sound right to you?

It is sunny here. We haven't had a lot of rain for quite a while. We did have a hail storm a few weeks back. The stones were quite big. Some were about the size of golf b***s and quite jagged. Any car outside was damaged and our plants got lots of holes in their leaves.
When i was a little girl, a very long time ago, we had hail as big as tennis b***s. They really did a lot of damage, they broke lots of windows and even broke people's bones. I still remember.
