Answer:
- Switch positions of two rows.
- Add elements of one row to another row.
- Multiply elements of one row by a scalar
Step-by-step explanation:
In general, each row represents a linear equation. The rules of equality apply. They allow you to multiply both sides of the equation by a scalar, add equal values to each side of the equation (add one row to another). Rearranging the sequence of equations (swapping rows) does not change the system or its solution.
