We need to solve the given matrix equation and it is given that matrix with entries 1, 9, 6 minus 6 is equal to matrix with entries minus 7 minus 9, 4, 5 multiplied with x plus matrix with entries 3, 4, 4, minus 3.
00:26
Now, by simplifying it, we have matrix minus 7, minus 9, 4, 5 multiplied with x is equal to matrix 1, 9, 6 minus 6 minus matrix with entries 3, 4, 4, minus 3.
00:46
Now, by simplifying it, we have minus 2, 5, 2, minus 3.
00:53
Now by comparing it with the matrix equation ax is equal to b we have the value of a is equal to minus 7 minus 9 4, 5.
01:09
Now by simplifying it we have x is equal to a inverse b.
01:15
We need to find the value of a inverse and for this we need to check the determinant of a which is equal.
