The system of equations are

$\"\"$ (Equation 1)

$\"\"$ (Equation 2)

$\"\"$ (Equation 3) and the ordered triple is $\"\"$ .

To check the solution,the values of $\"\"$ is substitute in system of equations.

$\"\"$ (Write original equation 1)

$\"\"$ (Substitute $\"\"$ )

$\"\"$ (Multiply)

$\"\"$

This is false, so the ordered triple $\"\"$ does not satisfy the equation 1.

So ordered triple $\"\"$ is not a solution of the system of equations. $\"\"$

No, the ordered triple $\"\"$ is not a solution of the system of equations.
