- Alter equations to omit variables.

The "eliminate" command is used to rewrite a set of simultaneous equations to omit the specified variable. Equations containing the variable are "solve"d in terms of that variable, and their right-hand sides are paired to form new equations. The original equations are automatically "remove"d, so the eliminated variable no longer appears in any equation.

Elimination can be used to simplify a set of equations by minimizing the number of equations and/or variables involved.

e.g. x+2y=8 Enter an equation containing "y".

y-3z=1 Enter another equation containing "y".

eliminate y Eliminate "y", leaving "(8-x)/2=1+3z"

Warning: Eliminating a variable that appears in only one equation will remove that equation. A prompt will ask if the elimination should proceed.
