This problem has one of the ugliest answers I have seen.
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
\n" ); document.write( "15x-4y=6
\n" ); document.write( "9x+2y=7 Multiply both sides times 2 and subtract from above:
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
\n" ); document.write( "15x-4y=6
\n" ); document.write( "18x+4y=14
\n" ); document.write( "---------
\n" ); document.write( "33x = 20
\n" ); document.write( "x= 20/33
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
\n" ); document.write( "Now solve for y
\n" ); document.write( "15x-4y=6 Multiply all times -3
\n" ); document.write( "9x+2y=7 Multiply all times 5
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
\n" ); document.write( "-45x+12y= -18
\n" ); document.write( "45x+10y= 35
\n" ); document.write( "-----------
\n" ); document.write( "22y= 17
\n" ); document.write( "y= 17/22
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
\n" ); document.write( "So there you have it:
\n" ); document.write( "x= 20/33
\n" ); document.write( "y= 17/22 \n" ); document.write( "

\n" );
