Calculator of System of Linear Equations

Last updated: Jan. 3, 2019
  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.
