what is the solution of the matrix equation?
[9,4,2,1] x = [-9,-6,-1,-8]
To find the solution of the matrix equation [9,4,2,1] x = [-9,-6,-1,-8], we need to solve for the vector x.
The equation can be rewritten as a system of linear equations:
9x + 4y = -9
2x + y = -6
1x = -1
1x = -8
Solving this system of equations, we get x = -1, y = -4.
Therefore, the solution to the matrix equation is x = [-1,-4].
