r in (-oo:+oo)

(7*r)/8 = (5*r-10)/3 // - (5*r-10)/3

(7*r)/8-((5*r-10)/3) = 0

(-1*(5*r-10))/3+(7*r)/8 = 0

(-1*8*(5*r-10))/(3*8)+(3*7*r)/(3*8) = 0

3*7*r-1*8*(5*r-10) = 0

80-19*r = 0

(80-19*r)/(3*8) = 0

(80-19*r)/(3*8) = 0 // * 3*8

80-19*r = 0

80-19*r = 0 // - 80

-19*r = -80 // : -19

r = -80/(-19)

r = 80/19
