Hi there,
\n" ); document.write( "Randy is three times as old as his brother Ben
\n" ); document.write( "R = 3B.........Eq(1)
\n" ); document.write( "six years ago the sum of their ages is the same
\n" ); document.write( "as Randy's present age.
\n" ); document.write( "R - 6 + B - 6 = 3B........Eq(2)
\n" ); document.write( "Replace R in Eq(2) with 3B from Eq(1)
\n" ); document.write( "3B - 6 + B - 6 = 3B
\n" ); document.write( "Collect like terms
\n" ); document.write( "3B - 3B + B = 6 + 6
\n" ); document.write( "B = 12
\n" ); document.write( "Randy is 36 years old
\n" ); document.write( "Brother is 12 years old.
\n" ); document.write( "Hope this helps :-)
