3-((27*x)/4) = x/2-((1/4)*(-3*x-4)) // - x/2-((1/4)*(-3*x-4))
(1/4)*(-3*x-4)-((27*x)/4)-(x/2)+3 = 0
(1/4)*(-3*x-4)+(-27/4)*x-(x/2)+3 = 0
1/4*(-3*x-4)+(-27*x)/4-x/2+3 = 0
(1/4*2*4*(-3*x-4))/(2*4)+(-27*2*x)/(2*4)+(4*(-x))/(2*4)+(2*3*4)/(2*4) = 0
1/4*2*4*(-3*x-4)-27*2*x+4*(-x)+2*3*4 = 0
24-60*x-4*x-8 = 0
24-64*x-8 = 0
16-64*x = 0
(16-64*x)/(2*4) = 0
(16-64*x)/(2*4) = 0 // * 2*4
16-64*x = 0
16-64*x = 0 // - 16
-64*x = -16 // : -64
x = -16/(-64)
