matrix%282%2C3%2C6%2C+-1%2C+3%2C-6+%2C7+%2C5%29 compare to matrix%282%2C3%2Ca11%2C+a12%2C+a13%2Ca21+%2Ca22+%2Ca23%29

a23+=5 and a11=6

In matrix A, a23 is the entry in row 2, column 3 -- or, informally, the 3rd entry in row 2. In the given matrix, that entry is 5.

Similarly, a11 is the 1st entry in row 1, which in the given matrix is 6.

ANSWERS: a23 = 5; a11 = 6
