\n" ); document.write( "In 12 years you will be = x+12\r
\n" ); document.write( "\n" ); document.write( "According to given condition
\n" ); document.write( "x+12=3(x-10)
\n" ); document.write( "x+12=3x-30
\n" ); document.write( "x-3x=-30-12
\n" ); document.write( "-2x=-42
\n" ); document.write( "Divide by -2 both sides
\n" ); document.write( "-2x/-2=-42/-2
\n" ); document.write( "x=21\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Your present age = x = 21 years old\r
