First, assign the variables.
\n" ); document.write( "Let H = Huilan's age
\n" ); document.write( "T = Thomas's age. \r
\n" ); document.write( "\n" ); document.write( "H = T + 6
\n" ); document.write( "H + T = 72 Subsitute H from the first equation into the second equation.\r
\n" ); document.write( "\n" ); document.write( "(T + 6) + T = 72 Solve for T.
\n" ); document.write( "2T + 6 = 72 Subtract 6 from both sides.
\n" ); document.write( "2T = 66 Divide both sides by 2.
\n" ); document.write( "T = 33 Thomas's age is 33 years.
\n" ); document.write( "H = T + 6 = 33 + 6 = 39 Huilan's age is 39 years.\r
\n" ); document.write( "\n" ); document.write( "Check:
\n" ); document.write( "T+6 = 33+6 = 39
\n" ); document.write( "T+H = 33+39 = 72 \n" ); document.write( "

\n" );
