Math Problem Statement

Solve for x and y given the matrix equation: \( \begin{bmatrix} x & -3 \\ 8 & 23 \end{bmatrix} = \begin{bmatrix} -5 & -3 \\ 8 & y \end{bmatrix} \)

Solution

To solve for xx and yy in this matrix equation:

[x3823]=[538y]\begin{bmatrix} x & -3 \\ 8 & 23 \end{bmatrix} = \begin{bmatrix} -5 & -3 \\ 8 & y \end{bmatrix}

we can equate corresponding elements from both matrices.

  1. For the top-left element: x=5x = -5

  2. For the bottom-right element: 23=y23 = y

So, the solutions are: x=5x = -5 y=23y = 23
