Solve the system by graphing, addition and substitution methods.
\n" ); document.write( "3x – y = 1 ..........1
\n" ); document.write( "3x – y = 2................2
\n" ); document.write( "eqn.1 - eqn.2
\n" ); document.write( "0=1-2=-1...not possible..hence no solution..they are in consistent eqns.
\n" ); document.write( "x...............0.......................2..............4......etc
\n" ); document.write( "y=3x-1.........-1.......................5..............11.....etc
\n" ); document.write( "y=3x-2.........-2.......................4...............10.....etc
\n" ); document.write( " $\"+graph%28+500%2C+500%2C+-10%2C+10%2C+-10%2C+10%2C%283%2Ax-1%29%2C+%283%2Ax-2%29%29+\"$
\n" ); document.write( "the 2 graphs are parallel and do not intersect hence there is no solution. \n" ); document.write( "

\n" );
