h in (-oo:+oo)
(2/3)*h-(4*((2/3)*h-3)) = (2/3)*h-6 // - (2/3)*h-6
(2/3)*h-(4*((2/3)*h-3))-((2/3)*h)+6 = 0
(2/3)*h-4*((2/3)*h-3)+(-2/3)*h+6 = 0
(2*h)/3-4*(2/3*h-3)+(-2*h)/3+6 = 0
(-4*3*(2/3*h-3))/3+(2*h)/3+(-2*h)/3+(3*6)/3 = 0
2*h-4*3*(2/3*h-3)-2*h+3*6 = 0
18-6*h-2*h+36 = 0
18-8*h+36 = 0
54-8*h = 0

(54-8*h)/3 = 0 // * 3
54-8*h = 0
54-8*h = 0 // - 54
-8*h = -54 // : -8
h = -54/(-8)
h = 27/4
