\n" ); document.write( "sol:
\n" ); document.write( "let ales age = x
\n" ); document.write( "fred age = y
\n" ); document.write( "in 5 years,
\n" ); document.write( "(x+5) = 3(y+5)---------- 1
\n" ); document.write( "present;
\n" ); document.write( "x + y = 86 ---------- 2
\n" ); document.write( "solve 1 & 2 as equations which gives x = 67 , y = 19
\n" ); document.write( "so after 3 years , x = 70 , y = 22 \n" ); document.write( "

\n" );
