 Hello and welcome to the session. Let us understand the following problem today that a is equal to matrix 2, 4, 3, 2, b is equal to matrix 1, 3, minus 2, 5 and c is equal to matrix minus 2, 5, 3, 4. Find 3a minus c. Now let us write the solution. Given to us is a is equal to 2, 4, 3, 2. So 3a is equal to 6, 12, 9, 6. And given to us c is equal to minus 2, 5, 3, 4. So minus c is equal to minus 5, minus 3, minus 4. Now 3a minus c is equal to 3a plus minus c which is equal to 3a is 6, 12, 9, 6. Plus minus c is 2, minus 5, minus 3, minus 4 which is equal to 6 plus 2, 8, 12 minus 5, 7, 9, minus 3, 6, 6, minus 4, 2. Therefore 3a minus c is equal to matrix 8, 7, 6, 2. I hope you understood the problem bye and have a nice day.
