x in (-oo:+oo)

(3*x-11)/5+x/20 = x/4-1 // - x/4-1

(3*x-11)/5+x/20-(x/4)+1 = 0

(3*x-11)/5+x/20-x/4+1 = 0

(4*20*(3*x-11))/(4*5*20)+(4*5*x)/(4*5*20)+(5*20*(-x))/(4*5*20)+(1*4*5*20)/(4*5*20) = 0

4*20*(3*x-11)+4*5*x+5*20*(-x)+1*4*5*20 = 0

260*x-100*x-880+400 = 0

160*x-880+400 = 0

160*x-480 = 0

(160*x-480)/(4*5*20) = 0
