The sum of the ages of a brother and sister is 26. If four times the brother's age is subtracted from three times the sister's age, the difference is 8.
First equation: 26 = s + b
2nd equation: 8 = 3s + 4b
- What are the ages of the brother and sister?

2. Suppose a matrix has four blocks A, B,C, D, where A is invertible. Block elimination can be done on this block matrix. For example, consider what happens when CA-1 times the first block row [A B] is subtracted from the second block row [C D 0 D - CA B Note: S = D-CA-B is called the Schur complement of A.
