Let x=number of years that elapses until I am 3 times the age of the youngest
\n" ); document.write( "Then 58+x=my age at that time
\n" ); document.write( "And 11+x=age of the youngest at that time
\n" ); document.write( "Sooooo:
\n" ); document.write( "58+x=3(11+x)
\n" ); document.write( "58+x=33+3x
\n" ); document.write( "58-33=2x
\n" ); document.write( "25=2x
\n" ); document.write( "x=12.5 years
\n" ); document.write( "58+x=58+12.5=70.5 -----my age when I am 3 time the age of the youngest
\n" ); document.write( "11+x=11+12.5=23.5------the youngest's age at that time\r
\n" ); document.write( "\n" ); document.write( "CK
\n" ); document.write( "3*23.5=70.5
\n" ); document.write( "70.5=70.5\r
