u in (-oo:+oo)

((7*u-5)^1)/2 = ((9*u-15)^1)/2 // - ((9*u-15)^1)/2

((7*u-5)^1)/2-(((9*u-15)^1)/2) = 0

(7*u-5)/2-((9*u-15)/2) = 0

(7*u-5)/2+(-1*(9*u-15))/2 = 0

7*u-1*(9*u-15)-5 = 0

10-2*u = 0

(10-2*u)/2 = 0

(10-2*u)/2 = 0 // * 2

10-2*u = 0

10-2*u = 0 // - 10

-2*u = -10 // : -2

u = -10/(-2)

u = 5
