You can put this solution on YOUR website!
x + y = 8
\n" ); document.write( "y = x - 3
\n" ); document.write( ":
\n" ); document.write( "Rearrange the 2nd equation, add to the 1st equation
\n" ); document.write( "x + y = 8
\n" ); document.write( "-x+ y = -3
\n" ); document.write( "-------------adding eliminates x find y
\n" ); document.write( "0 + 2y = 5
\n" ); document.write( "y = \"5%2F2\"
\n" ); document.write( "y = 2.5
\n" ); document.write( ":
\n" ); document.write( "Find x, the original 2nd equation
\n" ); document.write( "2.5 = x - 3
\n" ); document.write( "2.5 + 3 = x
\n" ); document.write( "5.5 = x
\n" ); document.write( ":
\n" ); document.write( "Ordered pair: 5.5, 2.5
\n" ); document.write( ":
\n" ); document.write( "Check solution in original 1st equation
\n" ); document.write( "x + y = 8
\n" ); document.write( "5.5 + 2.5 = 8
\n" ); document.write( " \n" ); document.write( "
\n" );
