x + 2y = 19
\n" ); document.write( " -x + 7y = 53
\n" ); document.write( "---------------Addition eliminates x find y
\n" ); document.write( "0 + 9y = 72
\n" ); document.write( "y = \"72%2F9\"
\n" ); document.write( "y = 8
\n" ); document.write( ":
\n" ); document.write( "Find x using the 1st equation
\n" ); document.write( "x + 2(8) = 19
\n" ); document.write( "x + 16 = 19
\n" ); document.write( "x = 19 - 16
\n" ); document.write( "x = 3
\n" ); document.write( ";
\n" ); document.write( "3,8 is the ordered pair
\n" ); document.write( ";
\n" ); document.write( "Check solutions in the 2nd equation
\n" ); document.write( "-3 + 7(8) =
\n" ); document.write( "-3 + 56 = 53
