60/x-1 = 36/1-x+12 // - 36/1-x+12
x+60/x-(36/1)-12-1 = 0
x+60/x-36-12-1 = 0
1*x^1+60*x^-1-49*x^0 = 0
(1*x^2-49*x^1+60*x^0)/(x^1) = 0 // * x^2
x^1*(1*x^2-49*x^1+60*x^0) = 0
x^1
x^2-49*x+60 = 0
x^2-49*x+60 = 0
DELTA = (-49)^2-(1*4*60)
DELTA = 2161
DELTA > 0
x = (2161^(1/2)+49)/(1*2) or x = (49-2161^(1/2))/(1*2)
x = (2161^(1/2)+49)/2 or x = (49-2161^(1/2))/2
x in { (49-2161^(1/2))/2, (2161^(1/2)+49)/2}
