Two linear equations
Solve two linear equations with two variables; cases with no solution or infinitely many solutions dey shown too.
a₁x + b₁y = c₁
a₂x + b₂y = c₂
Solve three linear equations with three variables; cases with no solution or infinitely many solutions dey shown too.
a₁x + b₁y + c₁z = d₁
a₂x + b₂y + c₂z = d₂
a₃x + b₃y + c₃z = d₃
Floating-point calculation fit give approximate results, especially when di equations nearly depend on each other.
