n for kuNal's age now
\n" ); document.write( "g for saGar's age now\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "6 years ago n-6 and g-6;
\n" ); document.write( "\"%28n-6%29%2F%28g-6%29=6%2F5\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "4 years in the future n+4 and g+4;
\n" ); document.write( "\"%28n%2B4%29%2F%28g%2B4%29=11%2F10\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "---- A table or chart was a strategy for this problem but the two equations just found are enough to solve the problem----\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Taking further steps with the equations gives us these:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "5(n-6)=6(g-6)
\n" ); document.write( "5n-30=6g-36
\n" ); document.write( "5n-6g=30-36
\n" ); document.write( "\"highlight%285n-6g=-6%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "10(n+4)=11(g+4)
\n" ); document.write( "10n+40=11g+44
\n" ); document.write( "10n-11g=44-40
\n" ); document.write( "\"highlight%2810n-11g=4%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Multiply the first one by 2 subtract it from the second one:
\n" ); document.write( "\"10n-11g-%2810n-12g%29=4-%28-12%29\"
\n" ); document.write( "\"-11g%2B12g=16\"
\n" ); document.write( "\"highlight%28g=16%29\" from which you can easily finish solving for n.
\n" ); document.write( "
\n" );
