x in (-oo:+oo)
x/5+y/5.8 = 40/5.5 // - 40/5.5
x/5+y/5.8-(40/5.5) = 0
x/5+y/5.8-7.27272727 = 0
1/5*x+0.17241379*y-7.27272727 = 0 // - 0.17241379*y-7.27272727
1/5*x = -(0.17241379*y-7.27272727) // : 1/5
x = (-(0.17241379*y-7.27272727))/1/5
x = 5*(7.27272727-(0.17241379*y))
x = 5*(7.27272727-(0.17241379*y))
