r in (-oo:+oo)
(5*(2*r-2))/7 = 5*r-(6/3) // - 5*r-(6/3)
(5*(2*r-2))/7-(5*r)+6/3 = 0
(5*(2*r-2))/7-5*r+6/3 = 0
(5*(2*r-2))/7-5*r+2 = 0
(5*(2*r-2))/7+(-5*7*r)/7+(2*7)/7 = 0
5*(2*r-2)-5*7*r+2*7 = 0
14-25*r-10 = 0
4-25*r = 0
(4-25*r)/7 = 0
(4-25*r)/7 = 0 // * 7
4-25*r = 0
4-25*r = 0 // - 4
-25*r = -4 // : -25
r = -4/(-25)
r = 4/25
r = 4/25
