2*((1/4)*x+1/2)+(7/4)*x-((3/2)*x) = (1/3)*(6/5-((9/2)*x)) // - (1/3)*(6/5-((9/2)*x))
2*((1/4)*x+1/2)-((1/3)*(6/5-((9/2)*x)))+(7/4)*x-((3/2)*x) = 0
2*((1/4)*x+1/2)+(-1/3)*((-9/2)*x+6/5)+(7/4)*x+(-3/2)*x = 0
2*(1/4*x+1/2)-1/3*(6/5-9/2*x)+(7*x)/4+(-3*x)/2 = 0
(4*2^2*(1/4*x+1/2))/(2*4)+(-1/3*2*4*(6/5-9/2*x))/(2*4)+(2*7*x)/(2*4)+(-3*4*x)/(2*4) = 0
4*2^2*(1/4*x+1/2)-1/3*2*4*(6/5-9/2*x)+2*7*x-3*4*x = 0
16*x+14*x-12*x+24/5 = 0
