x in (-oo:+oo)
(1/2)*(x+3)-x+3/2 = 5*x // - 5*x
(1/2)*(x+3)-x-(5*x)+3/2 = 0
(1/2)*(x+3)-x-5*x+3/2 = 0
1/2*(x+3)-x-5*x+3/2 = 0
(1/2*2*(x+3))/2+(2*(-x))/2+(-5*2*x)/2+3/2 = 0
1/2*2*(x+3)+2*(-x)-5*2*x+3 = 0
3-x-10*x+3 = 0
3-11*x+3 = 0
6-11*x = 0
(6-11*x)/2 = 0
(6-11*x)/2 = 0 // * 2
6-11*x = 0
6-11*x = 0 // - 6
-11*x = -6 // : -11
x = -6/(-11)
x = 6/11
x = 6/11
