\n" ); document.write( "Currently, sarah is three times her daughter's age.
\n" ); document.write( "s = 3d
\n" ); document.write( ":
\n" ); document.write( "In 13 years, she will be two times her daughter's age.
\n" ); document.write( "s + 13 = 2(d+13)
\n" ); document.write( "s + 13 = 2d + 26
\n" ); document.write( "s = 2d + 26 - 13
\n" ); document.write( "s = 2d + 13
\n" ); document.write( "replace s with 3d
\n" ); document.write( "3d = 2d + 13
\n" ); document.write( "3d - 2d = 13
\n" ); document.write( "d = 13 is the daughter's age
\n" ); document.write( "I'll let you find Sarah's age
