A level maths algebra help
Hi there
Please could someone help with this question, really rather simple but I'm at a blank at the moment..
how do I get from:
1/8y=1/2x
to become
4y=x
As per the screenshot attached, ignore the notation in the screenshot
Ya is just Y and YB is just x to make things simpler.

Multiplying both sides by a number, which is______________

well, multiplying both sides with 8y gives : 1= 8y/2x
then multiplying both sides with 2x gives : 2x = 8y
Dividing both side by 2 gives : x = 4y
There you go
then multiplying both sides with 2x gives : 2x = 8y
Dividing both side by 2 gives : x = 4y
There you go
Rubbish.

It is ridiculously over complicated and long winded with an unnecessary step.

Sorry.
Seeing that this guy cannot solve this problem I assumed it would not hurt to add the extra step.

Which step do you consider unnecessary

Still does the job regardless of the method.
As long as the OP understands the method, there's no problem.

Multiplying by 8y.
Don't patronise me.
I am not your pupil.

My bad was not aware of the forum rules about full solutions sorry.
No problem
The guidance encourages us to ask questions and develop understanding rather than give answers
You will know for next time
