(7/4)*x+1 = 6/x-5 // - 6/x-5
(7/4)*x-(6/x)+1+5 = 0
(7/4)*x-6*x^-1+1+5 = 0
7/4*x^1-6*x^-1+6*x^0 = 0
(7/4*x^2+6*x^1-6*x^0)/(x^1) = 0 // * x^2
x^1*(7/4*x^2+6*x^1-6*x^0) = 0

(7/4)*x^2+6*x-6 = 0
(7/4)*x^2+6*x-6 = 0
DELTA = 6^2-(-6*4*(7/4))
DELTA = 78
DELTA > 0
x = (78^(1/2)-6)/(2*(7/4)) or x = (-78^(1/2)-6)/(2*(7/4))
x = 2/7*(78^(1/2)-6) or x = -2/7*(78^(1/2)+6)
