Solution for 8/3=(v-9)/(7v+4) equation: 


D( v )

7*v+4 = 0

7*v+4 = 0

7*v+4 = 0

7*v+4 = 0 // - 4

7*v = -4 // : 7

v = -4/7

v in (-oo:-4/7) U (-4/7:+oo)

8/3 = (v-9)/(7*v+4) // - (v-9)/(7*v+4)

8/3-((v-9)/(7*v+4)) = 0

(-1*(v-9))/(7*v+4)+8/3 = 0

(-1*3*(v-9))/(3*(7*v+4))+(8*(7*v+4))/(3*(7*v+4)) = 0

8*(7*v+4)-1*3*(v-9) = 0

53*v+59 = 0

(53*v+59)/(3*(7*v+4)) = 0

(53*v+59)/(3*(7*v+4)) = 0 // * 3*(7*v+4)

53*v+59 = 0

53*v+59 = 0 // - 59

53*v = -59 // : 53

v = -59/53

v = -59/53
