Call the mother's age now, x. The daughter's age is y.
\n" ); document.write( "Thus x + y = 47, and x = 47 - y.
\n" ); document.write( "In five years,
\n" ); document.write( "x + 5 = 6 + 2(y + 5) or
\n" ); document.write( "x + 5 = 6 + 2y + 10
\n" ); document.write( "x + 5 = 2y + 16
\n" ); document.write( "x = 2y + 11
\n" ); document.write( "Substituting in, we get
\n" ); document.write( "47 - y = 2y + 11
\n" ); document.write( "36 = 3y
\n" ); document.write( "y = 12
\n" ); document.write( "x = 35
\n" ); document.write( "
\n" );
