Solution :

Check the attached picture.

Answer 2

Question:

if if X and Y are 2×2 matrices,then solve the following Matrices equation for X and Y ,

2X + 3Y = $X=\left[\begin{array}{cc}2&3\\4&0\end{array}\right]$

3X+2Y = $X=\left[\begin{array}{cc}-2&2\\1&-5\end{array}\right]$

Theory :

A rectangular arrangement of numbers in row and column is called a matrix.

Properties of Matrices:

1) Addition of Matrices

If A,B and C are matrices of same order then ,

• A+B = B+A
• (A+B)+C = A+(B+C)
• A+O = A ,where O is zero matrix

2)Scalar multiplication of Matrix

Let A= $(a_{ij})_{m\timesn}$ and k be a number

kA = Ak = $(ka_{ij})_{m\timesn}$

Solution :

$X=\left[\begin{array}{cc}-2&0\\-1&-3\end{array}\right]$

$Y=\left[\begin{array}{cc}2&1\\2&2\end{array}\right]$
