Let's call the son x and the father y
\n" ); document.write( "y = x+19 we'll use this value for y next
\n" ); document.write( "y+10 = 2(x+10)
\n" ); document.write( "x+19+10 = 2x+20
\n" ); document.write( "x+29 = 2x+20 subtract x and 20 on both sides
\n" ); document.write( "9 = x
\n" ); document.write( "or
\n" ); document.write( "x = 9 this is how old Pat is.
