1.618x=y
Swap sides so that all variable terms are on the left hand side.
\frac{1.618x}{1.618}=\frac{y}{1.618}
Divide both sides of the equation by 1.618, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{y}{1.618}
Dividing by 1.618 undoes the multiplication by 1.618.
x=\frac{500y}{809}
Divide y by 1.618 by multiplying y by the reciprocal of 1.618.
