What is Matrix?

A matrix is a set of numbers organized in rows and columns to create a rectangular array. The numbers exist named the elements, or entries, of the matrix. Matrices include wide applications in engineering, physics, economics, and statistics as well as in different branches of mathematics.

A matrix exists a rectangular structure of a collection of numbers into a fixed number of rows and columns so that we can complete arithmetic operations (addition, multiplication, etc.) on them”. The simple description of a matrix is that it is an array of numbers (that can be real or complex) contained in rows and columns.

Given,

$f\left[\begin{array}{cc}-1 & -2 \\4 & 8\end{array}\right]+X=\left[\begin{array}{cc}-5 & -1 \\2 & 1\end{array}\right]$

Step 1

$f\left[\begin{array}{cc}-1 & -2 \\4 & 8\end{array}\right]+X=\left[\begin{array}{cc}-5 & -1 \\2 & 1\end{array}\right]$

$\left[\begin{array}{cc}-4 & 1 \\-2 & -7\end{array}\right]$

Hence, The x is $\left[\begin{array}{cc}-4 & 1 \\-2 & -7\end{array}\right]$
