let x= present dad age; y=present son age
\n" ); document.write( "establis the equation as follows:
\n" ); document.write( "x-20=y .........(1)
\n" ); document.write( "x+5=3(y+5) .....(2)\r
\n" ); document.write( "\n" ); document.write( "take (1) subtract from (2) we have:
\n" ); document.write( "x+5-x+20 = 3y+15-y
\n" ); document.write( " 2y= 25-15
\n" ); document.write( " 2y = 10
\n" ); document.write( " y = 5
\n" ); document.write( "Present son age is 5 years old and Dad present age is x= x+20=5+20
\n" ); document.write( " x= 25 years old
