Label the columns, separate LHS and RHS by dotted line, and write the row operations on the LHS of the new matrix. To avoid too much writing, during the row operations, use only one matrix to convert all entries below one pivot to 0. Circle the pivots. State when row reduction is complete. Solution must be in vector or vector parametric form. Book Reading (60%): Section 1.2: 1. Example 2. a. Show that [2, 0, 0, 1] is/is not a solution of the system. b. Find the solution by row reduction. State the relationship between the number of solutions and the number of pivots. 2. Example 3 Solve the system by row reduction. State the relationship between the number of pivots and the number of solutions. 3. Example 4 Solve the system by row reduction. State the relationship between the number of pivots and the number of solutions. 4. Practice Problem 2. Solve the system by row reduction. State the relationship between the number of pivots and the number of solutions. What is the general solution? What are 2 particular solutions?
