I am doing my GCSE maths and a question has come up in one of my text books. I have looked through all of my notes but found nothing like this question.

4 - (x - 3 ) = 6 - 4x

I have tried soooooo hard to work this out, but i know there is a way to do this. Mathematically, there is a way to do this.

PLEASE could some one tell me how to work these wuestions out.

Good Luck.

Alright well im not exactly sure what GCSE is but x = - (1/3), but if thats not what your looking for here is a link i found about this stuff

Na, im still confused. hehe, thanks for your help thought.

GCSE is the course we do in the United Kingdom, it is the equivalent to O Levels, if you have heard of them and we do them before you can leave school at 16 but if you dont get good grades in them then you can go to an advanced collage and resit them. Its basically easy maths. But as you can see, im not too good at it.

alright well here i ll show u the work to your problem
[Initial Equation] 4 - ( x - 3 ) = 6 - 4x
first lets get rid of the annoying paraenthesis, there is a - sign out in front of them so take the - and multiply it times the x and the -3. and ull get
[Step 1] 4 - x + 3 = 6 - 4x
Now lets simplify the left side by adding like terms, which are the 4 and 3
[Step 2] 7 - x = 6 - 4x
Now lets get x on one side
[Step 3] 7 - x + x = 6 - 4x + x
That simplified is
[Step 4] 7 = 6 - 3x
now lets get x alone on one side so subtract 6
[Step 5] 7 - 6 = 6 - 3x - 6
That simplified is
[Step 6] 1 = - 3x
Now the task of getting x all by its lonesome, to do this divide both sides by -3 or by multiplying by its reciprical which would be (-1/3)
[Step 7] 1 * (-1/3) = -3x * (-1/3)
The -3s cancel each other out on the right side so that leave the answer as
[Final Answer] (-1/3) = x
So x equals negative one-third

If you are 16, and that equation baffles you, then you what you really need is a professional maths tutor.

Yeah, if you're this far and none of your notes have single-variable algebraic equations then I'm not so sure why everyone bashes the American education system.

Of course, it could be as ElderKnight suggested and the poster meant to post a multi-variable equation. Even then, it's not that tough to bring it down to x + 4y = -1, which has several solutions. (I just noticed how much of Linear Equations I have forgotten in the past 3 months... such a shame, I loved the class.)

Yeah...I rememeber stuff like that in 8th grade. Just remember please excuse my dear aunt sally. Thats the order of precedence. Thats the basics. Please=Parenthesis, Excuse=Exponentiation,My=Multiply,Dear=Divison,Aunt=Addition, Sally=Subtraction. Its a good method to remember the basics of precedence.

Does everybody really bash the American education system?

Hmmm... seems rather easy to do... but then I wouldn't have a leg to stand on in commenting on that since I'm the product of an entirely private education and my mother retired from teaching to raise my sister and I... not to mention all the music lessons!

I think complaints about numeracy and literacy skills of school-leavers are common, certainly they are in both Australia and the UK.

Some people had the bright idea in the 80's that certain skills (I'm sorry, that should read competencies ) that had been traditionally regarded as important, were really over-emphasised, and should now be optional ...

You know, old-fashioned things like the ability to count, to read, to spell, to speak and to write .....

Unfortunately, these people were actually in charge of curriculum development

I'm at school in the UK (well, pretty much) and we'd done quadratic equations, linear equations, factorising etc. before entering the GCSE course. The teacher taught us a lot, but this year it's back to the textbook with my new teacher. Pick of the draw

here in Canada I think the education system is pretty good .(in ontario that is anyway) Math is a pain, calc, geometry and discrete, finite, and all the fun stuff. But even though i consider school hard enough here, I hear about in other places outside of N america, where they do crazy long days 6 days week, etc etc. Sounds very unfun to me lol and I'm glad when I hear that mentioned I live here.

I took Algebra of this level in elementry, but I'm uber- so don't take me as normal or nothing. I did Geometry in 9th, Analytical Geometry/Trig in 10th, taking Calc now (in 12th) I took pre-calc last year...

I don't like Calculus, the Fancy F's are so hard to draw right...

We Need a math for non-artisticly-inclined people...
