3x+y=-13
\n" ); document.write( "-x+2y=2
\n" ); document.write( "-----
\n" ); document.write( "Modify for elimination:
\n" ); document.write( "3x + y = -13
\n" ); document.write( "-3x + 6y = 6
\n" ); document.write( "---------------
\n" ); document.write( "Add and solve for \"y\":
\n" ); document.write( "7y = -7
\n" ); document.write( "y = -1
\n" ); document.write( "-------
\n" ); document.write( "Solve for \"x\":
\n" ); document.write( "-x+2y = 2
\n" ); document.write( "-x - 2 = 2
\n" ); document.write( "x = -4
