Solution for 3=(8v-8)/(7)+(5v+7)/(4) equation: 


v in (-oo:+oo)

3 = (8*v-8)/7+(5*v+7)/4 // - (8*v-8)/7+(5*v+7)/4

3-((8*v-8)/7)-((5*v+7)/4) = 0

(-1*(8*v-8))/7+(-1*(5*v+7))/4+3 = 0

(-1*4*(8*v-8))/(4*7)+(-1*7*(5*v+7))/(4*7)+(3*4*7)/(4*7) = 0

3*4*7-1*4*(8*v-8)-1*7*(5*v+7) = 0

84-67*v-17 = 0

67-67*v = 0

(67-67*v)/(4*7) = 0

(67-67*v)/(4*7) = 0 // * 4*7

67-67*v = 0

67-67*v = 0 // - 67

-67*v = -67 // : -67

v = -67/(-67)

v = 1

v = 1
