Hey if someone knows how to solve this please provide a short solution!

y = x + 4 / x - 1

The question asks to represent "x"

The correct answer is:

4 + y / y - 1

do you just sub in x for y? if so, then is 4 + y, in the numerator, just a trick?

Im trying to figure this crap out...but if anyone beats me to it...then feel free to post.

y = (x + 4) / (x - 1)

y (x - 1) = x + 4

yx - y = x + 4

yx - x = y + 4

x(y - 1) = y + 4

x = (y + 4) / (y - 1)

good luck!

really appreciate it, thanks!
