$[\begin{array}{c} 4 & - 6 \\ 3 & x \end{array}] = [\begin{array}{c} 4 & y \\ 3 & - 9 \end{array}]$

Passaggio 1

Write as a linear system of equations.

$4 = 4$

$- 6 = y$

$3 = 3$

$x = - 9$

Passaggio 2

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

Infinite solutions satisfying the system.
