# Calculator of System of Linear Equations

The following are input forms that solve two, three, or four-variable system of linear equations.
Enter the coeffients and the constant terms of the linear equations, and press "Execute" button. The solution set is displayed.
Two-variable system
 $x$ + $y$ = $x$ + $y$ =
$x$ =
$y$ =
Three-variable system
 $x$ + $y$ + $z$ = $x$ + $y$ + $z$ = $x$ + $y$ + $z$ =
$x$ =
$y$ =
$z$ =
Four-variable system
 $x$ + $y$ + $z$ + $u$ = $x$ + $y$ + $z$ + $u$ = $x$ + $y$ + $z$ + $u$ = $x$ + $y$ + $z$ + $u$ =
$x$ =
$y$ =
$z$ =
$u$ =
Usage notes:
$\circ$ The calculation result is output as decimal.
$\circ$ If the system of linear equations is inconsistent or indeterminate, "infinty" or "NaN" will be displayed.
