Unformatted text preview: and not for the other. 3. Solve the following systems of linear equations by hand using the GJ elimination method. Use pivot elements of 1 or1 as far as possible to avoid the occurrence of fractions. If system inconsistent, obtain a solution to the alternate system in each case. How many solutions of the alternate system were you able to obtain?
