By graphing the lines on the coordinated plane they will intersect at (2, -4) which is the solution of the equations

3x + 2y = 62x + 3y = -1You can use substition, elimation, or graphing to solve this system, but I prefer to use matrices. They are difficult to type out, but the answer is x = 4 and y = -3.

The solution consists of the infinite number of points on the line which is defined by y + x = 6.

Check your text book for how to solve it.

Where the lines intersect that gives the values for x and y in the two equations. The lines should intersect at (1, -3) because x = 1 and y = -3
2x + 2y = 44x + y = 1There are many methods you can use to solve this system of equations (graphing, elimination, substitution, matrices)...but no matter what method you use, you should get x = -1/3 and y = 7/3.

Yes you can, if the solution or solutions is/are real. -- Draw the graphs of both equations on the same coordinate space on the same piece of graph paper. -- Any point that's on both graphs, i.e. where they cross, is a solution of the system of equations. -- If both equations are linear, then there can't be more than one such point.
