Algebra help needed
I was trying to get the a variables on one side of the equation and the b variables on the other side of the equation but I couldn't. Can anyone else separate these two variables?
( P.S. The equation is in the attached document.) Thanks for helping!!!

(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).
