(1.01*10^5+(9.81*10*13534)/100)*(0.4-x) = 1.01*10^5*(x+0.4) // - 1.01*10^5*(x+0.4)
(1.01*10^5+(9.81*10*13534)/100)*(0.4-x)-(1.01*10^5*(x+0.4)) = 0
(1.01*10^5+(9.81*10*13534)/100)*(0.4-x)-1.01*10^5*(x+0.4) = 0
114276.854*(0.4-x)-101000*(x+0.4) = 0
114276.854*(0.4-x)-101000*(x+0.4) = 0
5310.7416-215276.854*x = 0
5310.7416-215276.854*x = 0
5310.7416-215276.854*x = 0 // - 5310.7416
-215276.854*x = -5310.7416 // : -215276.854
x = -5310.7416/(-215276.854)
x = 0.02466936
x = 0.02466936
