You can put this solution on YOUR website!
  1. Get the equations into \"standard\" form: Ax + By = C. Your first equation is already in this form. All we need to do with the second is to rewrite it as an addition:
    \n" ); document.write( "3x + (-4y) = 8
  2. Then just write the numbers into a matrix, leaving out all the \"punctuation\" (addition, =, parentheses, etc.):
    \n" ); document.write( "
    \r\n" );
    document.write( "+-            -+\r\n" );
    document.write( "|  1   1   5   |\r\n" );
    document.write( "\r\n" );
    document.write( "|  3  -4   8   |\r\n" );
    document.write( "+-            -+\r\n" );
    document.write( "

    \n" ); document.write( "(I apologize for the crude matrix \"corners\".)

\n" ); document.write( "
