I suck at Algebra. I failed it both times I took it. So I'm taking it again, this time I'm actually working. But I cant figure out this problem.
4x+1/2(12x+2)=3 Help? |

Just distribute the 1/2 to the numbers in parenthesis first so you get:
4x+6x+1=3 Subtract 1 from both sides and combine like terms: 10x=2 Divide both sides by 10. x=2/10 Reduce. x=1/5 |

I did it and got that same process and result. Just remember to distribute what you can. Usually it'll help. Combine whatever terms you can. Basically, just simplify it as much as possible and see what you get. |

3/2(x+8) = 12
Distribute 3/2x + 12 = 12 Move over the 12 3/2x = 0 x must equal 0 Do you see how it follows the same pattern as the first? You distribute the term to the parenthesis, collect like terms, and solve from there. In this case distributing the term is a bit odd, but it works out. You'll just have to give it a try. The next one you have trouble with post what you've done as well. You can read answers all day, but you've got to know how to do it come test time. You've got to understand the how and the why.

I am embarrassingly bad at math.
The highest math I have taken here in college, and will ever take, is Finite Math, which is the equivalent of 9th grade high-school mathematics. I can explain the Federalist Papers inside and out, but God help me if I have to do a basic algebra problem. Edited by Man Bites Dog - 04 October 2007 at 2:40pm |

Well I see enough people have helped already. Might I ask which algebra this is?
I simply think you need some motivation to learn algebra. I recently read a book written by an engineer, he describes ways of solving problems, thinking, and learning. One of his main points is that if you don't have the desire to do something, you might as well not do it. Well, it seems to me you don't care about it, so you don't do well. Work harder at it if you want to go to upper level maths. This is the stuff we have to be able to figure out very quickly in our head in my calculus class. My teacher gave us a quiz, 10 algebra problems. We had 5 minutes, no calculator, and the only thing we could write down were answers. The maximum you could miss was 1/2 of 1 point, otherwise, you take it again until you do pass it. |

I'm actually pretty glad that BioStats 2 is the last 'math class' that I ever have to take.

I'm surprised that this many people are concerned with algebra. Not to sound ignorant of those who have difficulty with math, but isn't this like grade-school stuff?
