$[\begin{array}{c} 3 & 4 \\ - 8 & 1 \end{array}] = [\begin{array}{c} 3 & x \\ y & z \end{array}]$

Bước 1

Write as a linear system of equations.

$3 = 3$

$4 = x$

$- 8 = y$

$1 = z$

Bước 2

Since $3 = 3$ is always true, the matrix equation has infinite solutions.

Infinite solutions satisfying the system.
