Description
Examples
eliminate (eqnset, varset)
eqnset
-
set or list of equations
varset
variable, or set or list of variables to eliminate from the equations
eliminate eliminates the given variables from a set or list of equations.
The result of this elimination is an expression sequence of lists. Each list represents a possible elimination of the given variables.
The first component of each solution is a set of equations, where the left-hand side of these equations is a variable (one of the variables in varset) and the right-hand side is its corresponding value. The second component of each solution is the set of remaining equations once the varset have been eliminated.
Eliminate the variable x from a list of equations.
