Question
Obtain an equivalent system by performing the stated elementary operation on the system. Multiply the
first
equation by
1/9.
| 9x | − | 5y | + | 3z | = | 18 |
| 5x | − | 5y | − | 8z | = | 10 |
| 2x | − | 3y | + | 2z | = | 8 |
| 9x | − | 5y | + | 3z | = | 18 |
| 5x | − | 5y | − | 8z | = | 10 |
| 2x | − | 3y | + | 2z | = | 8 |
→
| x | − | y | + | z | = | |
| x | − | y | − | z | = | |
| x | − | y | + | z | = |
(Type integers or simplified fractions.)
