How does y = 4?
Could anyone help me reach the correct answer, step by step?
I'm stumped again.
Any help with 7b would be much appreciated. I'm getting 3/7, which is extremely different to the text book answer (4).

Show us what you have done.
Oh but it's so embarrassing to be such a math fail. You're all maths geniuses and I suck at thissss.
Anyway:
-4/3 divided by -4/3 + 1
=
4/3 divided by 7/3
= 4 x 3 = 12
3 x 7 = 21
= 3/7
Anyway:
-4/3 divided by -4/3 + 1
=
4/3 divided by 7/3
= 4 x 3 = 12
3 x 7 = 21
= 3/7

I have been trying to get your incorrect answer but it does not fit with any error I can see

-4/3 + 1 doesn't equal -7/3

AND
even if that bit were correct

If I were to research this further (via online tutorials) what kind of topic should I be looking up? Do I look up 'finding x in fractions'?
Ok so that's where I'm going wrong. How does it equal that? What's the arithmetic?

No - you need to learn how to add, subtract, and divide fractions
It is not the algebra that is the issue it is your arithmetic
Oh okay. Thank you very much.

Oh gosh. Maybe it should be 4/7.
But I can't work out how -4/3 + 1 = - 1/3. How do you reach that?

I do not understand what you are asking
3 - 4 = -1
You are subtracting 1 instead of adding it

Right. Sorry. It's so obvious when it's pointed out.

Don't apologise
As I said you need to practice some arithmetic with fractions before continuing with the algebra
Yes, I clearly must practice simple arithmetic first.
Thank you again for your help.
Thank you again for your help.
x = -4/3 (4/3)/(4/3)-1 so its 1 I think

You've bumped a thread from 5 years ago, so I don't think the OP needs this any more
And the answer is y = 4 as stated in the oriignal post.
