In t years the man will be 30 + t years old
\n" ); document.write( "in t years the son will be 4+t years old.
\n" ); document.write( "in t years the man (30+t) will be twice 2* as old as the son (4+t) \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "30+t=2(4+t)
\n" ); document.write( "30+t=8+2t
\n" ); document.write( "subtract 8 from both sides
\n" ); document.write( "22+t=2t=t+t
\n" ); document.write( "and subtract t from both sides
\n" ); document.write( "22=t
\n" ); document.write( "In 22 years the man will be 52 and the son will be 26.
