Solution for 28=(4w-1)/5+(9w+3)/4 equation: 


w in (-oo:+oo)

28 = (4*w-1)/5+(9*w+3)/4 // - (4*w-1)/5+(9*w+3)/4

28-((4*w-1)/5)-((9*w+3)/4) = 0

(-1*(4*w-1))/5+(-1*(9*w+3))/4+28 = 0

(-1*4*(4*w-1))/(4*5)+(-1*5*(9*w+3))/(4*5)+(4*5*28)/(4*5) = 0

4*5*28-1*4*(4*w-1)-1*5*(9*w+3) = 0

560-61*w-11 = 0

549-61*w = 0

(549-61*w)/(4*5) = 0

(549-61*w)/(4*5) = 0 // * 4*5

549-61*w = 0

549-61*w = 0 // - 549

-61*w = -549 // : -61

w = -549/(-61)

w = 9

w = 9
