Feel stupid about this

Rearrange to make X the subject
Y= -X/4

Normally I know how to do this but i keep getting -X= 4Y note the X has to be positive. Can somebody help

-X/4 is the same as X/(-4)

Try multiplying both sides of the first equation by -4 and see what you get.

If you read

Try dividing.....

you didn't misread it. That's what I wrote first but quickly changed it having realised I'd made a mistake.

EDIT: Was going to type some advice here but I just read that you got the solution. Nice one

Simply multiply each side by -1: X = -4Y
