Answer:
11x+2y+21 x = 15
2x+3y+6z = -29
13x+9x+2x =22
Step-by-step explanation:
This is an augmented matrix
It is the coefficients of the variables and the last number is the constant
11x+2y+21 x = 15
2x+3y+6z = -29
13x+9x+2x =22
![x \leq -2\\ (- \alpha ,-2]](https://tex.z-dn.net/?f=x%20%20%5Cleq%20-2%5C%5C%0A%28-%20%5Calpha%20%2C-2%5D%20)
Note: the infinity character would not render correctly, so I used alpha instead. Pretend it's an infinity sign.
Answer:
