Let
\n" ); document.write( "Present age of Craig = c
\n" ); document.write( "Present age of Father = f\r
\n" ); document.write( "\n" ); document.write( "Craig is 28 years younger means if we add 28 to the present age of Craig, both father and son will be of equal age
\n" ); document.write( "f=c+28 ........(1)
\n" ); document.write( "Sum of their ages
\n" ); document.write( "c+f=64.........(2)
\n" ); document.write( "Put the value of f from (1) to (2)
\n" ); document.write( "c+(c+28)=64
\n" ); document.write( "c+c+28=64
\n" ); document.write( "2c+28=64
\n" ); document.write( "2c=36
\n" ); document.write( "Divide by 2 both sides of above equation
\n" ); document.write( "2c/2=36/2
\n" ); document.write( "c=18
\n" ); document.write( "Put the value of c in (1)
\n" ); document.write( "f=c+28 ........(1)
\n" ); document.write( "f=18+28
\n" ); document.write( "f=46\r
\n" ); document.write( "\n" ); document.write( "Present age of Craig = c = 18 years old
\n" ); document.write( "Present age of Father = f = 46 years old\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
