x in (-oo:+oo)
(1/4)*x+1/5 = (9/8)*(5*x+11) // - (9/8)*(5*x+11)
(1/4)*x-((9/8)*(5*x+11))+1/5 = 0
(-9/8)*(5*x+11)+(1/4)*x+1/5 = 0
x/4-9/8*(5*x+11)+1/5 = 0
(-9/8*4*5*(5*x+11))/(4*5)+(5*x)/(4*5)+(1*4)/(4*5) = 0
5*x-9/8*4*5*(5*x+11)+1*4 = 0
4-215/2*x-495/2 = 0
-215/2*x-487/2 = 0
(-215/2*x-487/2)/(4*5) = 0
(-215/2*x-487/2)/(4*5) = 0 // * 4*5
-215/2*x-487/2 = 0
-215/2*x-487/2 = 0 // + 487/2
-215/2*x = 487/2 // : -215/2
x = 487/2/(-215/2)
x = -487/215
x = -487/215
