Let x=son's age
\n" ); document.write( "Then x+5=daughter's age
\n" ); document.write( "8x=father's age
\n" ); document.write( "Also 4(x+5)=father's age, so:
\n" ); document.write( "8x=4(x+5) get rid of parens
\n" ); document.write( "8x=4x+20 subtract 4x from each side
\n" ); document.write( "8x-4x=4x-4x+20
\n" ); document.write( "4x=20 divide each side by 4
\n" ); document.write( "x=5--------------son's age
\n" ); document.write( "x+5=5+5=10 daughter's age
\n" ); document.write( "8x=8*5=40-----------father's age\r
\n" ); document.write( "\n" ); document.write( "CK
\n" ); document.write( "8*5=4(5+5)
\n" ); document.write( "40=40\r
