solve for x
y=(x-9)/(3x-1)
(3x-1)y=x-9
3xy-y=x-9
3xy-x=y-9
x(3y-1)=y-9
x=(y-9)/(3y-1)

that's the answer i get... the book answer says x=(y+9)/(1-3y)

is my math wrong or is that the same answer just written different?
 
Your math is good. If the book had (-y+9) it would be "just written different."
