If you are trying to solve for phi then:
(a + b)/(a) = a/b = phi where a > b, and b not equal to 0
Since a/b = phi, cross multiply to get a = b*phi
Substitute b*phi for a giving;
(b*phi + b)/(b*phi) = (b*phi)/b
Cross multiply to get;
(b^2)*phi^2 = (b^2)*phi + b^2
(b^2)*phi^2 = (b^2)(phi + 1)
phi^2 = phi + 1
phi^2 - phi - 1 = 0
Solve for phi. phi = (1 + sqrt(5))/2 (Ignore the (1 - sqrt(5))/2 case).
