A man is 8 years older than his wife
\n" ); document.write( "m = w+8
\n" ); document.write( "or
\n" ); document.write( "w = m-8
\n" ); document.write( " and 6 times as old as his son.
\n" ); document.write( "m = 6s
\n" ); document.write( " When the son was born, the age of the wife was four-fifth of her husband.
\n" ); document.write( "w - s = \"4%2F5\"(m-s)
\n" ); document.write( "get rid of the denominator, multiply by 5
\n" ); document.write( "5(w-s) = 4(m-s)
\n" ); document.write( "5w - 5s = 4m - 4s
\n" ); document.write( "5w = 4m - 4s + 5s
\n" ); document.write( "5w = 4m + s
\n" ); document.write( "replace w with (m-8)
\n" ); document.write( "5(m-8) = 4m + s
\n" ); document.write( "5m - 40 = 4m + s
\n" ); document.write( "5m - 4m = s + 40
\n" ); document.write( "m = s + 40
\n" ); document.write( "replace m with 6s
\n" ); document.write( "6s = s + 40
\n" ); document.write( "6s - s = 40
\n" ); document.write( "5s = 40
\n" ); document.write( "s = 40/5
\n" ); document.write( "s = 8
\n" ); document.write( ":
\n" ); document.write( " Find the age of the sun now?
\n" ); document.write( "They say 4.6 billion years, but you probably meant the \"son\"
\n" ); document.write( "son is 8 yrs old
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this, man is 48, wife is 40
\n" ); document.write( "\"When the son was born, the age of the wife was four-fifth of her husband. \"
\n" ); document.write( "40 - 8 = \"4%2F5\"(48-8)
\n" ); document.write( "32 = \"4%2F5\"(40)
\n" ); document.write( " \n" ); document.write( "
\n" );
