You can put this solution on YOUR website!
Let +x+ = Daryl's age now
Start at the end of the problem
"before he is twice as old as he is now"
That is: +2x+
"eight years before he is twice as old as he is now"
That is: +2x+-+8+
"Today, Daryl is two thirds as old as he will be. . '
This says:
+x+=+%282%2F3%29%2A%28+2x+-+8+%29+
+3x+=+2%2A%28+2x+-+8+%29+
+3x+=+4x+-+16+
+x+=+16+
------------
Daryl is 16
check:
+x+=+%282%2F3%29%2A%28+2x+-+8+%29+
+16+=+%282%2F3%29%2A%28+2%2A16+-+8+%29+
+48+=+2%2A%28+32+-+8+%29+
+24+=+32+-+8+
+24+=+24+
OK
