a in (-oo:+oo)
(a-3)/5-((5*(a-3))/8) = (5*a+25)/4 // - (5*a+25)/4
(a-3)/5-((5*(a-3))/8)-((5*a+25)/4) = 0
(a-3)/5+(-5/8)*(a-3)-((5*a+25)/4) = 0
(a-3)/5-5/8*(a-3)+(-1*(5*a+25))/4 = 0
(4*(a-3))/(4*5)+(-5/8*4*5*(a-3))/(4*5)+(-1*5*(5*a+25))/(4*5) = 0
4*(a-3)-5/8*4*5*(a-3)-1*5*(5*a+25) = 0
51/2-17/2*a-25*a-125 = 0
-67/2*a-199/2 = 0
(-67/2*a-199/2)/(4*5) = 0
(-67/2*a-199/2)/(4*5) = 0 // * 4*5
-67/2*a-199/2 = 0
-67/2*a-199/2 = 0 // + 199/2
-67/2*a = 199/2 // : -67/2
a = 199/2/(-67/2)
a = -199/67
a = -199/67
