sum of two numbers: $\"x%2By=47\"$
\n" ); document.write( "difference: $\"x-y=15\"$
\n" ); document.write( " $\"x\"$ has to be larger then $\"y\"$ to get a possitive $\"15\"$
\n" ); document.write( "so i would use elimination method to solve for $\"x\"$
\n" ); document.write( " $\"x%2By=47\"$
\n" ); document.write( " $\"x-y=15\"$ add the equations together straight down
\n" ); document.write( " $\"2x%2B0=62\"$
\n" ); document.write( " $\"highlight%28x=31%29\"$ x is the largest number
\n" ); document.write( "___________
\n" ); document.write( "check
\n" ); document.write( " $\"31%2By=47\"$
\n" ); document.write( " $\"y=16\"$
\n" ); document.write( " $\"31-y=15\"$
\n" ); document.write( " $\"-y=-16\"$
\n" ); document.write( " $\"y=16\"$
\n" ); document.write( "16=16 so its correct. \n" ); document.write( "

\n" );
