Solve. (Enter your answers as a comma-separated list. If there are infinitely many solutions, enter a parametric solution. If there is no solution, enter NONE.)

2x | + | 2y | + | 2z | = | 16 |

6x | + | 6y | + | 6z | = | 41 |

3x | + | 3y | + | 4z | = | 31 |

(*x*, *y*, *z*) =

Solve the following system of equations. (Enter your answers as a comma-separated list. If there are infinitely many solutions, enter a parametric solution using *t* and/or *s*. If there is no solution, enter NONE.)

x_{1} |
− | 2x_{2} |
+ | x_{3} |
= | −1 |

2x_{1} |
+ | x_{2} |
− | 2x_{3} |
= | 1 |

x_{1} |
+ | 3x_{2} |
− | 3x_{3} |
= | 2 |

(x_{1}, x_{2}, x_{3}) =

Step 1
