determined whether the equation from a linear system

×- y +z = Cos()

3X - Y + Z = 2

Solution

x- y +z = Cos()

3X - Y + Z = 2

A system of linear equations (or linear system) is a collection of two or more linear equations involving the same set of variables.

In the second equation 3X - Y + Z = 2 , it doesn\'t have the same set of variables like in first equation.
