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 3 for y in each of the original equations.
Substitute for x and 3 for y in the equation 1:
.
.
The above statement is not true, so is not a solution of equation 1.
Because is not a solution of equation 1, it is not a solution of the linear system.
The ordered pair is .
