$[\begin{array}{c} t - 4 & 8 & - 7 \\ 8 & 7 & - 5 \end{array}] = [\begin{array}{c} 8 & 8 & - 7 \\ 8 & X - 9 & - 5 \end{array}]$

Langkah 1

Write as a linear system of equations.

$t - 4 = 8$

$8 = 8$

$- 7 = - 7$

$8 = 8$

$7 = X - 9$

$- 5 = - 5$

Langkah 2

Since $- 5 = - 5$ is always true, the matrix equation has infinite solutions.

Infinite solutions satisfying the system.
