4x-6y=12
\n" ); document.write( "6x-9y=15
\n" ); document.write( "--------------
\n" ); document.write( "Divide thru the 1st equation by 2.
\n" ); document.write( "Divide thru the 2nd equation by 3.
\n" ); document.write( "----
\n" ); document.write( "2x - 3y = 6
\n" ); document.write( "2x - 3y = 5
\n" ); document.write( "----
\n" ); document.write( "Subtract:
\n" ); document.write( "0 = 1
\n" ); document.write( "-----
\n" ); document.write( "That contradiction occurred because I assumed
\n" ); document.write( "the x's were the same and the y's were the
\n" ); document.write( "same in the two equations.
\n" ); document.write( "---
\n" ); document.write( "They are not.
\n" ); document.write( "The system is inconsistent.
\n" ); document.write( "The lines are parallel.
\n" ); document.write( "There is no solution for this system of equations.
