Q in (-oo:+oo)
11 = (1400-(2*Q))/46 // - (1400-(2*Q))/46
11-((1400-(2*Q))/46) = 0
11-((1400-2*Q)/46) = 0
(-1*(1400-2*Q))/46+11 = 0
(-1*(1400-2*Q))/46+(11*46)/46 = 0
11*46-1*(1400-2*Q) = 0
2*Q-894 = 0
(2*Q-894)/46 = 0
(2*Q-894)/46 = 0 // * 46
2*Q-894 = 0
2*Q-894 = 0 // + 894
2*Q = 894 // : 2
Q = 894/2
