Math Problem Statement

Solve the matrix equation [4 1]X = [-4 8; -1 2]

Solution

The given matrix equation is:

[41]X=[4812]\begin{bmatrix} 4 \\ 1 \end{bmatrix} X = \begin{bmatrix} -4 & 8 \\ -1 & 2 \end{bmatrix}

To solve this, we need to recognize that this is a system of equations. The vector [41]\begin{bmatrix} 4 \\ 1 \end{bmatrix} represents the unknown variables multiplied by the matrix on the right-hand side. This means the equation can be written as two simultaneous equations.

  1. First row of the matrix: 4x1+1x2=44x_1 + 1x_2 = -4
  2. Second row of the matrix: 4x1+1x2=84x_1 + 1x_2 = 8

We can solve these equations by standard methods of solving a system of
