(1904/2014)*X+x+2*x+3*x+4*x+5*x = 305083/1007 // - 305083/1007
(1904/2014)*X+x+2*x+3*x+4*x+5*x-(305083/1007) = 0
(1904/2014)*X+x+2*x+3*x+4*x+5*x-16057/53 = 0
952/1007*X+15*x-16057/53 = 0 // - 952/1007*X-16057/53
15*x = -(952/1007*X-16057/53) // : 15
x = (-(952/1007*X-16057/53))/15
x = (16057/53-(952/1007*X))/15
x = (16057/53-(952/1007*X))/15
