Is there a forum with homework help or can someone help me here?

Lotsa luck there...it took me 2 years to pass algebra (geometry is MUCH easier) and I'll tell you what....I've never ever used it...I do not care what
x =........it should be abolished...along with those, "two trains leave different stations at the same time" problems....Hey, I know..let's ban math period!!!
LMFAO @ lethal fang.
To the OP: if you can type it down I can probably help you, algebra isn't hard and I've taken Calculus.
ditto, it has happened before.
i had 2 courses of algebra and 3 calculus. I almost dont recall anything, but like mastermind said, it isnt that hard.
I'm takin AP Calc right now as a sophmore and lemme tell ya, if you have trouble with algebra (I breezed through it), you're in for a hell of a time.
Its a lot harder than pre-cal, alg II, alg but could be worse I guess.

Wow, did you skip a grade or two? Because I'm a junior taking AP Calc, no sophomores at all.
By the way, did you start derivatives and limits? So far, Calc has been easy (can't say the same for the teacher).
And to the OP, algebra isn't really hard. Write down the problem and I'll try to help you with it (if I remember).
Post problems you have trouble with and someone (I'll help when it's something I know) will help you out.
Math for the sake of math had driven me crazy before college. Schools need to show people how to apply what they have learned. Check the web, though. You can find sites that break it down for you with good anaologies. My advice, learn the applications and it will stick better. Otherwise it is like learning a language without the intention of speaking it.
Multiply the 2nd eqtn by -2 and you'll get the ff:Two missing factors
3x+4y=1
2x+2y=1
Multiply the 2nd eqtn by -2 and you'll get the ff:
3x + 4y = 1
-4x -4y = -2
Add the two equations together to solve for x:
-x = -1
or
x = 1
Using this value for x, substitute this in either of the first two equations to solve for y (I'll use the 1st one):
3(1) + 4y = 1 => 4y = -2
or
y = -1/2
Solving systems of linear equations is so easy!
Just messin' with ya! This happens to be one of my favorite math topics when I was in high school.ouch idk if i got a bit of that but my work book went from a problem like
You did this one correctly, for what it's worth.5x+7=8x+4
5x-5x+7-4=8x+4-4-5x
7-4=8x-5x
3=3x
3.....3x
- = .. -
3......3
1=x
to something like that last problem and i am lost

Oh,...well i didnt mean the problem i just did that i finally got that but the one with two equations i didnt understand a word
Oh,...
That problem you listed is what is called system of linear equation. There is a solution if the number of unknown variables (here, x and y) is equal to the number of equations given. The trick is to multiply one of the equations by a number so that when you add it to another one, one of the variables will be eliminated, thus simplifying the system to the point that you can solve for remaining variable.

Two missing factors
3x+4y=1
2x+2y=1
and for future reference how would i type brackets
Wow....I did that in my head mate, come on! Give us something harder!
Here's another easy one for you, Duzza.......
What's the value of (1-i)^12, where i is the sqrt(-1)?
Let's see you expand that in your head
I was about to post that your x value should have been negative but it seems that you were able to edit it.
Good job! See how easy it is?
Two thumbs up!
LOL that would be nice.Lotsa luck there...it took me 2 years to pass algebra (geometry is MUCH easier) and I'll tell you what....I've never ever used it...I do not care what

Ive never heard of a school that just let you skip math courses just because you want to lol. And alg 1 was incredibly easy lol. I literally slept through most classes because i had it first period and i aced it easily lol. But what ap cal are you taking? AB or BC?yes, we haved dived into the world of derivitives, limits, and other stuff...
as for geometry, yeah, i hated geometry. So I skipped it. So happy i did it, cause we had to do formal proofs.
I took algebra II and either got sleep or did my homework while my teacher blabbed on.
I skipped pre-cal cuz my parents told me to.
ok need help again
1/2x+1/3y=2
x-1/3y=1
and another one
x-3y=7
2x-2y=18
