what is the equation of the line?

Answer 1

I mean, what is the equation to the line x=15y/(x-2)
in terms of y?
(y=...)

Answer 2

Multiply both sides by (x-2)
that gets you
(x-2)x = 15y
then do the opposite of times by 15 to both sides of the equation : )

Answer 3

x=15y/(x-2)
multiply both sides by x-2
x^2 - 2x = 15y
divide both sides by 15
y = ...
