 Hello friends, welcome to the session I am Elka. We are going to discuss matrices. Our given question is, find x and y if x plus y equal to matrix 7025 and x minus y equal to matrix 3003. Now let's start with the solution. We are given with the values of x plus y and x minus y. We name it as our first equation and this x minus y is our second equation. Now on adding equation first and second we get 2x equal to 7025 plus 3003. This can also be written as 2x equal to 7 plus 3, 0 plus 0, 2 plus 0 and 5 plus 3. Therefore 2x equal to 10, 0, 2, 8. This implies x equal to 1 by 2 of 10, 0, 2, 8. Therefore x equal to 5014. Now we will calculate the value of y. On subtracting equation second from equation first we get 2y equal to 7025 minus 3003. This implies 2y equal to, this implies 2y equal to 7 minus 3, 0 plus 0, 2 plus 0, 5 minus 3. This implies 2y equal to 4022. Therefore y equal to 1 by 2 of the matrix 4022. This implies y equal to 2011. Hence x equal to 5014 matrix and y equal to 2011 matrix. Hope you understood it and enjoy the session. Goodbye and take care.
