You can put this solution on YOUR website!
Start by writing equations..We know that:\r
\n" ); document.write( "\n" ); document.write( "x+y=7
\n" ); document.write( "x-y=23 we can use the elimination process by adding the two equations together and solving\r
\n" ); document.write( "\n" ); document.write( "so:
\n" ); document.write( "2x = 30
\n" ); document.write( "x = 15\r
\n" ); document.write( "\n" ); document.write( "Now put it back in and solve:\r
\n" ); document.write( "\n" ); document.write( "15 + y = 7
\n" ); document.write( "y = -8\r
\n" ); document.write( "\n" ); document.write( "So your answer is (15,-8)
\n" ); document.write( "
\n" );
