In equation systems {determinative system} {consistent system} {simultaneous system}, number of independent equations can equal number of variables, and all variables have numerical solutions. Number of independent equations can be less than number of variables {inconsistent system}, so not all variables have numerical solutions. If some equations are equivalent to others {dependent system}, not all variables have numerical solutions. Number of independent equations can be more than number of variables {overdetermined system}.
