\n" ); document.write( "Let the year difference be \"x\" yrs.
\n" ); document.write( "Equation:
\n" ); document.write( "my age then = 3(sister's age then)
\n" ); document.write( "(32+x) = 3(18+x)
\n" ); document.write( "32+x = 54 + 3x
\n" ); document.write( "2x = -22
\n" ); document.write( "x = -11
\n" ); document.write( "--------------
\n" ); document.write( "I will be 32-11 = 21
