Let one number be x, and the other can be y.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The sum of the two \"x%2By\" is 143, so \"x%2By=143\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "One of the numbers (x) is (=) 49 less (-49) than the other (y), or \"x=y-49\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Substitute:\r
\n" ); document.write( "\n" ); document.write( "\"x%2By=143\"
\n" ); document.write( "\"%28y-49%29%2By=143\"
\n" ); document.write( "\"2y-49=143\"
\n" ); document.write( "\"2y=192\"
\n" ); document.write( "\"y=96\"\r
\n" ); document.write( "\n" ); document.write( "Now that we know that \"y=96\", we can insert this value for y into \"x=y-49\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x=96-49=47\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Last step -- VERY IMPORTANT: Check your answer.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "96 + 47 = 143, and
\n" ); document.write( "96 - 47 = 49, so the answers check.
\n" ); document.write( "
\n" );
