(3*(M-1))/2+m/5 = 2*M-6 // - 2*M-6
(3*(M-1))/2-(2*M)+m/5+6 = 0
(3*(M-1))/2-2*M+m/5+6 = 0
(3*5*(M-1))/(2*5)+(-2*2*5*M)/(2*5)+(2*m)/(2*5)+(2*5*6)/(2*5) = 0
3*5*(M-1)-2*2*5*M+2*m+2*5*6 = 0
2*m-5*M-15+60 = 0
2*m-5*M+45 = 0
(2*m-5*M+45)/(2*5) = 0
(2*m-5*M+45)/(2*5) = 0 // * 2*5
2*m-5*M+45 = 0
x belongs to the empty set
