a system of linear is called overdetermined if it has more equations than variables. Give examples of overdetermined systems that have no solution, exactlyone solution and infite solutions

True or false: Whenever two equations in a system have the same coefficient for one of the variables, the elimination method is a good choice for solving.

Graph the systems of linear equations to determine the values of x and y that simultaneously satisfy both equations (if such values exist).  Note:  If the solution is an ordered pair, do not put spaces between the comma and the second value.  If the solution is "no solution" or "infinitely many solutions," enter those words with spaces and spelled correctly.

If the graphs of a system of two equations are both circles, what are the possible numbers of solutions (with real coordinates) of this system?
