what should I do next

- Callisto

cancel the common factors

- Callisto

wait not exactly correct

- Callisto

for the first fraction, the upper part, you should take 6 as the common factor

- pokemon23

true

now it makes sense

can you do it once again from the start, it's very messy

- anonymous

that answer is correct, just not in lowest terms

your other previous answer (42/2x-4) was more correct.
when doing simplification, it helps to.... simplify, to see what needs to be done more clearly. for most problems you don't need to do this, but later it gets helpful to think along these lines:

21

basically im saying 42/2(x-4) is the same thing as 42/2 * 1/(x-4)
42/2 is pretty simple arithmetic. Once you've got that simplified, just fit that back in to the expression.. and you've got the answer.
thats one of many ways to simplify things.

im a bit confused

- pokemon23

isn't it 2(x-2)

- Callisto

- anonymous

indeed. you could also divide by two.|dw:1332401294326:dw|

- anonymous

really the entire point is it does not matter how you simplify, as long as you are dividing or multiplying by "1", or keeping the overall expression equal.
you'll never end up with an incorrect answer this way lol
