Bill is 3 times as old as Nancy.
\n" ); document.write( "In 12 years Bill will be twice as old as Nancy.
\n" ); document.write( "How old are Bill and Nancy now?
\n" ); document.write( "-----------------
\n" ); document.write( "Equations:
\n" ); document.write( "b = 3n
\n" ); document.write( "(b+12) = 2(n+12)
\n" ); document.write( "-------------------
\n" ); document.write( "Substitute for \"b\" and solve for \"n\":
\n" ); document.write( "3n+12 = 2n+24
\n" ); document.write( "n = 12 yrs old (Nancy's age now)
\n" ); document.write( "---
\n" ); document.write( "Since b = 3n, b = 3*12 = 36 yrs old (Bill's age now)
