x in (-oo:+oo)
2*(1/2-4*x) = (2/3)*x+41/2 // - (2/3)*x+41/2
2*(1/2-4*x)-((2/3)*x)-(41/2) = 0
2*(1/2-4*x)+(-2/3)*x-41/2 = 0
2*(1/2-4*x)+(-2*x)/3-41/2 = 0
(3*2^2*(1/2-4*x))/(2*3)+(-2*2*x)/(2*3)+(-41*3)/(2*3) = 0
3*2^2*(1/2-4*x)-2*2*x-41*3 = 0
6-52*x-123 = 0
-52*x-117 = 0
(-52*x-117)/(2*3) = 0
(-52*x-117)/(2*3) = 0 // * 2*3
-52*x-117 = 0
-52*x-117 = 0 // + 117
-52*x = 117 // : -52
x = 117/(-52)
x = -9/4
