PLEASE HELP SOSOSOSOSOS

Consider this system of equations
{10x + 13y + 15z = 4
{ 12x - 2y + 5z = - 8
{ 2x + 2y - 6z = 4
The system can be represented by the following matrix equation where A is a 3 x 3 matrix and ⇾b is a 3D vector

[ x
A [ y = ⇾b
[ z

Find A and ⇾b

Answer 1

The given system of equations can be represented in matrix form as:

| 10 13 15 | | x | | 4 |

| 12 -2 5 | x | y | = |-8 |

| 2 2 -6 | | z | | 4 |

Therefore, the matrix A is:

| 10 13 15 |

| 12 -2 5 |

| 2 2 -6 |

And the vector ⇾b is:

| 4 |

|-8 |

| 4 |
