The equations of linear system are and the ordered pair is .
To tell the ordered pair is a solution of linear system, substitute for x and 0 for y in each of the original equations.
Substitute for x and 0 for y in the equation 1: .
.
Substitute for x and 0 for y in the equation 2: .
.
The above statement is not true, so is not a solution of equation 2.
Because is not a solution of equation 2, it is not a solution of the linear system.
The ordered pair is .
To tell the ordered pair is a solution of linear system, substitute 0 for x and
