You can put this solution on YOUR website!
Each ordered pair is simply (x,y). For instance, (0,4) can written as x=0 and y=4.
\n" ); document.write( "So to see if the solutions work, plug them into the equation
\n" ); document.write( "\"3x-y=12\"
\n" ); document.write( "


\n" ); document.write( "\"3%280%29-4=12\"check to see if 1st pair works
\n" ); document.write( "\"-4=12\" false
\n" ); document.write( "


\n" ); document.write( "\"3%284%29-0=12\"check to see if 2nd pair works
\n" ); document.write( "\"12=12\" true
\n" ); document.write( "


\n" ); document.write( "\"3%28-1%29-15=12\"check to see if 1st pair works
\n" ); document.write( "\"-3-15=12\"
\n" ); document.write( "\"-18=12\" false (edit: sorry I read the problem wrong)
\n" ); document.write( "So only (4,0) is the only solutions. \n" ); document.write( "

\n" );
