\n" );
document.write( "Let Fiza's and Mom's current ages be F and M, respectively
\n" );
document.write( "Then, ________2F = M + 6____M = 2F - 6 ----- eq (i)
\n" );
document.write( "Also, M + F = 75 ------ eq (ii)
\n" );
document.write( "2F - 6 + F = 75 ------- Substituting 2F - 6 for M in eq (ii)
\n" );
document.write( "2F + F = 75 + 6
\n" );
document.write( "3F = 81
\n" );
document.write( "F, or Fiza's current age = , or 27
\n" );
document.write( "In 10 years' time, Fiza will be 27 + 10, or  years-old\r
