x in (-oo:+oo)
(-1/4)*(x-8)+(1/5)*(x+2) = x+9 // - x+9
(-1/4)*(x-8)+(1/5)*(x+2)-x-9 = 0
1/5*(x+2)-1/4*(x-8)-x-9 = 0
1/5*(x+2)-1/4*(x-8)-x-9 = 0
12/5-1/20*x-x-9 = 0
12/5-21/20*x-9 = 0
-21/20*x-33/5 = 0
-21/20*x-33/5 = 0
-21/20*x-33/5 = 0 // + 33/5
-21/20*x = 33/5 // : -21/20
x = 33/5/(-21/20)
x = -44/7
x = -44/7
