What is Matrices?

A matrix is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns, which is used to represent a mathematical object or a property of such an object.

Here,

[tex]\left[\begin{array}{ccc}3&-1&3\\8&-1&-9\\4&-1&0\end{array}\right] - \left[\begin{array}{ccc}a&e&d\\f&b&h\\c&g&i\end{array}\right] = \left[\begin{array}{ccc}7&0&1\\-4&-5&1\\9&7&-4\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc}3-a&-1-e&3-d\\8-f&-1-b&-9-h\\4-c&-1-g&0-i\end{array}\right] =\left[\begin{array}{ccc}7&0&1\\-4&-5&1\\9&7&-4\end{array}\right][/tex]

On comparing both sides, we get

3-a = 7                   ⇒ a = -4

-1-e = 0                  ⇒ e = -1

3-d = 1                   ⇒ d = 2

8-f = -4                  ⇒ f =12

-1-b = -5                ⇒ b = 4

-9 - h = 1               ⇒ h =-8

4-c = 9                  ⇒ c = -5

-1-g = 7                 ⇒ g = -8

-i = -4                    ⇒ i = 4

Thus, the values of b = 4, e = -1, a = -4,  c = -5.
