Question

Which of the following represents x = 1/3y written in general form?

1/3x - y = 0
3x - y = 0
x - 1/3y = 0

Answer 1

$x= \frac{1}{3}y$ put all numbers on the left 
$x- \frac{1}{3}y=0$
third equation is the answer
$x- \frac{1}{3}y=0$ multiply by 3
3x-y=0

Answer 2

$x=\frac{1}{3}y\ \ \ \ \ \ \ \ \ |substract\ \frac{1}{3}y\ from\ both\ sides\\\\\boxed{x-\frac{1}{3}y=0}\\\\x-\frac{1}{3}y=0\ \ \ \ |multiply\ both\ sides\ by\ 3\\\\\boxed{3x-y=0}$
