x in (-oo:+oo)
25*(10*x+8) = (1/125)*(4-(2*x)) // - (1/125)*(4-(2*x))
25*(10*x+8)-((1/125)*(4-(2*x))) = 0
25*(10*x+8)+(-1/125)*(4-2*x) = 0
25*(10*x+8)-1/125*(4-2*x) = 0
25*(10*x+8)-1/125*(4-2*x) = 0
31252/125*x+24996/125 = 0
31252/125*x+24996/125 = 0
31252/125*x+24996/125 = 0 // - 24996/125
31252/125*x = -24996/125 // : 31252/125
x = -24996/125/31252/125
x = -6249/7813
x = -6249/7813
