I am not sure if you are supposed to plug in the -3x into the other problem in question one.  I am not sure if you are supposed to just add the x and y values and then solve for y in problem 2.  Are you supposed to use cramers rule for problme three.  Please help me I am struggling with these problems.  I need somebody to help understand the process of each problem so I will understand the problems come test time on Monday. Thanks for your time and help it is greatly appreciated.\r<BR>\n" );
